copper rivets, flat top rivets, flat head rivets, includes washers, 3/32 x 3/16, leather fastening, 50 pack, rivet leather

You get 50 solid copper flat head rivets and 50 washers. See the example how it looks attached to leather on both sides. I use the leather hole maker, baby ball peen hammer on and a plastic mallet.
I used a wood board to cut the hole in the lather with the punch and plastic mallet. I then placed the rivet into the hole flipped over and slipped the washer on and bloomed the rived end with the small ball peen hammer on a steel block.
