The snaps from Tandy are awful! They are expensive and you get like 10-20...and they are weak snaps! They pop real easy...so if you are putting them on a bracelet chances are you will lose it after about a week!
They should have them at Johann's or Frank's or whatever big store that has sewing and crafts stuff. I get mine from boot supply shop that is for shoemakers, I get 100 heavy duty snaps for about 12 bucks, brass , silver or copper, they sell boxes of 1,000 but that is 20 per part per box so 80 bucks, but I just buy 100 at a time and that lasts a while:) I think I bought 100 silver ones 5-6 months ago and I use 2 snaps per bracelet. I use the same ones for everything, wallets,belts,bracelets,cases....Heavy Duty! NOT LINE 24!!!!!!!! THEY SUCK!!!!!!
If you are in a pinch just seek out a Cobbler/ Shoe repair guy local and either buy some from them or ask where they order their snaps from. It may be a local supplier.
