Packaging for button sets

Does anybody else sell button sets or just singles? I was wondering what sort of packaging you do? This is what we did and wondered if we are on the OK track. I don't have a photo of the back, sorry. We just cut four sets of two slits and slipped the pin through the slots. The back also has our logo and site address on it. Let me know if you think this looks good or if you think we should do something else. In case the photos do not take, here is a link as well to it in our Etsy shop Pinback button set
