These small screw pin D shackles make a great add on to your wallet chain attachment if you're looking for something with a little more "play" or have a unique clasp that doesn't quite fit. — But these aren’t just for Wallet Chain Attachments, the “Extra Small Brass Bow Shackle” is integrated into Anvil’s Chains to install various clasps!

Extra Small Bow 5mm -This solid brass shackle is best used to install various clasps to Anvil Chains
Small Bow SS 8mm & Small Bow Brass 7mm - Work best for our pocket wallets like the Sarasota and Money Clip Wallets
Black 10mm & Gun Metal 9mm - This is the next size up & Recommended for any Full-size Anvil Chain Wallets, the black coating is durable. (Knurled Thumb Screw)
Stainless Slip-Pin 10mm - Very unique Slip Pin acts a lot like your Sockets & has a built-in spring-loaded ball bearing that allows the pin to slip into place (strong springball keeps pin in place nicely)
