Commonly Asked Questions

Materials Used

We use a premium quality stainless steel that allows our products to remain durable and brilliant, and they do contain about 10% - 14% nickel. Our collars do not contain any silver.

For those concerned about metal allergies, our titanium products are a great alternative with the added bonus of less weight.

Any of our stainless steel (Original Collection) items contain a small amount of nickel and may irritate the skin if you have a metal allergy.

However, our Titanium Collection is 100% hypoallergenic, allergy-free and will not react to sunlight, salt water, sweat, or body oils.

We do offer a 365 day return policy, so if you find one of our products is uncomfortable or irritates your skin, you can return it for a full refund.

Our collars, cuffs and anklets are approximately .3125 (516) inches (8mm) although we have a thicker .375 inches (1cm) option available for some collars in limited supply. Please contact us to check availability if you are interested in a thicker collar.

It depends on size, but our typical stainless steel collar weighs around 5 to 6 ounces. However, our titanium slave collars weigh around 3 to 4 ounces.

Generally speaking, our titanium collars are about 40% - 45% lighter than the regular stainless steel collars, which is about 2 to 3 ounces depending on the size. This is about the same percentage on the anklets and cuffs as well.

All of our titanium items are made from Grade 5 Titanium which has an excellent combination of strength, corrosion resistance, and biocompatibility. In addition to titanium, this grade is also comprised of 6% aluminium, 4% vanadium, and up to 0.25% iron.

For our rigid collars we use a 2mm Allen Key with an M4 (4mm), 0.7mm x 5mm cup point socket screw.

Our locking flexible collars (rope and chain) use a smaller .05" Allen Key with a 4-40 x 1/4" socket set screw.

Replacement key sets are available for both sizes.

We use a medical-grade Titanium Nitride on most of our items, although we may also use Zirconium Carbon Nitride. Both finishes are very durable and bio compatible while very closely resembling the look of real 18k Gold.

We have coated them in pure 18K gold in the past but found the finish did not tend to hold up with daily or prolonged wear.

Yes, every locking item comes with a hex screwdriver and two extra screws. We also offer replacement key sets that come with two allen keys and two extra screws if you want an extra set, as well as extra screwdrivers and a master key of you need a little something more.

Our stainless steel chains and some of the fasteners we use (like the screws in the collars) are made using a cold forming, or cold working, process.

We use an austenitic stainless steel (grade 316) in our products, which is generally a non-magnetic material in it's normal annealed (slow cooled) state.

However, once this metal is cold worked (cold forming is the process of bending and shaping the stainless steel to form the links or base of the screws), the stress and extreme pressure of this process may cause the stainless steel to develop a response to a magnet even though the fundamental make-up of the stainless steel has not changed.

We use a 316 marine grade grade stainless steel, which is commonly used for biomedical implants and considered a surgical grade stainless steel. This grade does contain about 10% - 14% nickel and does not contain any silver.

Wear and Comfort

Generally speaking, our titanium collars are about 40% - 45% lighter than the regular stainless steel collars, which is about 2 to 3 ounces depending on the size. This is about the same percentage on the anklets and cuffs as well.

It depends on size, but our typical stainless steel collar weighs around 5 to 6 ounces. However, our titanium slave collars weigh around 3 to 4 ounces.

Both out titanium and stainless steel collars are durable and resistant to corrosion, so prolonged exposure to moisture is fine, including swimming, bathing and any other water-based activity.

However, our stainless steel products should not have prolonged exposure salt water environments (especially warm) as they could potentially stain, especially in the cracks and crevices. While occasional exposure is fine, swimming in salt water is not recommended while wearing a stainless steel collar, cuff or anklet.

Titanium collars, cuffs and anklets are durable in any prolonged wet environment.

If you do wear your Eternity collar, cuff or anklet in the water, we suggest taking additional care to clean and dry the item thoroughly when done. When cleaning, never use harsh chemicals or cleaners as these could damage the surface and reduce the durability in wet conditions.

Yes, all of our collars, cuffs and anklets are safe to wear in a tanning bed if you don't mind the tan lines. If you are doing a spray-on tan, your item might smudge your tan so speak with your tanning pro about what to do.

All of our products will hold up fine in a dry or moist-air sauna, however, we strongly recommend not wearing either in any sauna or steam room. They will heat up to an uncomfortable level and with the amount of metal surface could become uncomfortable or even cause a mild burn, and trying to remove them in a hurry, should you need to, is problematic.

If you must, at least wrap your collar, cuff, or anklet in a small towel to keep the metal surface away from your skin and keep a spare key nearby (but outside of the heat).

Our collars, cuffs and anklets are approximately .3125 (516) inches (8mm) although we have a thicker .375 inches (1cm) option available for some collars in limited supply. Please contact us to check availability if you are interested in a thicker collar.

Sizing

Finding the right size largely depends on you and how you depend on wearing your collar, bracelet or anklet. However, we have created some sizing guidelines you should review for guidance, including how to measure. Our recommendations are based on what most people will find comfortable and we strongly recommend following our suggestions as a starting point.

However, we do offer a 365-day return/exchange policy, so if the size you order does not quite fit we are glad to exchange it.

We do not offer custom sizes. We have carefully created size options to comfortably accommodate a very wide variety of people, while maintaining a high-level of quality. However, if there is a size you would like to see, please let us know. If we see enough interest in a size, we will add it.

Screws and Locks

Yes, every locking item comes with a hex screwdriver and two extra screws. We also offer replacement key sets that come with two allen keys and two extra screws if you want an extra set, as well as extra screwdrivers and a master key of you need a little something more.

We provide replacement screws for a nominal fee - just order the replacement locking set. We also offer reduced shipping if ordering just the replacement set. Be sure to order the correct size and color for your item.

For our rigid collars we use a 2mm Allen Key with an M4 (4mm), 0.7mm x 5mm cup point socket screw.

Our locking flexible collars (rope and chain) use a smaller .05" Allen Key with a 4-40 x 1/4" socket set screw.

Replacement key sets are available for both sizes.

Engraving

Yes. All we need is your SLRN and we will take care of the rest. Please keep in mind we need to crop the size of the barcode to fit the pendant, so instead of a square barcode it is more of a rectangle - but we think you'll agree it looks better that way.

Yes. We can engrave any symbol or artwork you want from any black and white artwork you provide (we can take jpeg, png, gif, pdf, psd or eps). To get the artwork on your pendant, include the instructions in your order and send us your art using our form.

However, the art must be in pretty good shape to come out looking great, so if you have some crappy image you grabbed off the web don't just send it. Contact us first as we can probably get something of better quality for you.

We offer a variety of font styles for engraving. The following are the standard fonts we offer. If there is a specific font style your are looking for, please contact us and we will do our best to accommodate you.

Available Font Styles

Not at this time. Our engraving equipment is limited to small jewelry items like pendants and lockets. We hope to offer more engraving options in the future.

Travel Concerns

Generally we say yes, but your experience will depend on the airport, the equipment you walk through, and the TSA officer.

Our items are all non-magnetic, so most likely you will only encounter a problem if you are required to walk through an imaging machine and the TSA officer flags you for inspection. In this case, you may be subject to additional screening.

Therefore, if you prefer not to take off your item when traveling, we strongly recommend bringing your allen key just in case you need to remove your item. Also, remember to bring an additional screw, or two, just in case you lose one in the process.
