Frequently I get asked where I buy my locking Allen key clasps for my collars so that someone can use them on a collar that they made or to turn a sentimental necklace into a locking day collar. But the truth is I don't buy them. These babies are made by me from the ground up. From the initial concept, to the 3D model, to the molds, the wax models, the rough casting trees, and the final polished clasp that goes on my collars -- it's all done by my hands in my small batch casting studio. I don't source them from anywhere else or have them mass produced by a large casting house. So you know a lot of love goes into making each one. (These pictures show just some of the stages each clasp goes through.) But that doesn't mean you can't have one to use on your own collar. I gladly sell them for individual personal use at the link below so you can turn any necklace, choker, or bracelet into your very own locking day collar. -- https://www.etsy.com/listing/465994799
