These ID holders are exactly what I was hoping for. I do a lot of work at conventions and related shows, and badges are almost always involved in some case. A lot of artists have even started creating their own mock-badges to sell because they look cool or are similar to a video game's style! These were perfect for my personal intentions because they sealed individually so the pieces I have are safe inside of them without fear of getting wet or otherwise damaged by outside causes other than folding. The downside is they all come stuck together and seem a little cloudy until they are pulled apart from each other, which was a tad annoying to need to deal with, but nothing particularly difficult.
Pros: Seals & protects whats inside!
Cons: Badges stick to each other
