Mine came with a little blue tool that I place the snaps in. I had heard that this one is easier than the hammer tool and I think it is great. I have to use a rubber mallet with it though. This is what I have: Crafts, Etc! ® - 16K Snap Fastener Attacher Kit
Hope that helps!! If anyone heres of wholese for the snaps, please let me know. I would love to get some!!!
