Hi...it comes with the items in the container, I believe some are snaps but I need to look again...can you tell from the picture? You get everything in the pic:))
Were you the one that asked me about them? I tried finding your message to let you know I thought I found some...I wasn't sure if you needed snaps or rivets so I just thought I would list them and hoped you would find them:)
I would imagine most hobby stores like hobby lobby or michaels would carry them....maybe even Home Depot...I'm not sure but that would be a place to start...they were given to me so I am not sure where it was purchased:)
