I recently opened a game I had gotten in a trade a long time ago and saw that the cards are strapped together using these plastic/rubber static cling strips. They seem to stay tight together as intended and of course open easily also.
Since this was a trade from a while ago I have no idea who I got it from, but am interested in getting more of these straps for my other games' cards.
Does anyone know about these? I tried searching for these in various ways on amazon and google but didn't come up with much.
