Prior to April 1, 2025, the hardener on the anchor part of the clasp, or the "T", was a high performance industrial grade adhesive. As of April 2025, we have switched to a rubber adhesive made for repairing tires.
This rubber adhesive is less likely to harden or become brittle over time (thus less chance of cracking), and it has high strength, long-lasting viscosity and high-temperature resistance, ensuring that the bonded rubber items will remain intact even at high temperatures. It is also waterproof.
Because bicycle tubes are inherently soft, we added adhesive to the clasp for two main reasons:
1) To make the anchor "firm." This makes it easier to pull the anchor clasp through the hole when putting on your bracelet, necklace or choker.
2) For an added level of protection against tugging. The anchor shape was designed to make sure that the clasp does not come undone, however the adhesive helps to keep your jewelry on even if gets tugged by a shirt or jacket.
If you purchased a jewelry item prior to April 1, 2025, that uses the high performance industrial grade adhesive, and you have a crack, you can repair crack it with super glue or exchange it. We are happy to exchange it for one with the new rubber adhesive. Contact us if you would like to make an exchange.
