Do you have a pile of shiny Pokemon TCG coins that are sitting in a tin somewhere? Print these card-sized holders and put those coins into a card binder that you will never open instead!
I also included a slightly thinner version (carded) that you can glue other cards onto (see the energy card photos? Those are normal cards glued onto the thinner 3D prints then cut with an x-acto knife) I had some success using 3M Super 77 spray glue; the kind that looks like a can of spray paint. Just be careful with the overspray cause that stuff will hold onto your coins FOREVER.
