This print is a way to upcycle any old or unused Pokemon TCG mini tins! It is an insert that allows you to transform it into a Nintendo Gameboy Micro case. I added a strip of velcro (or could use double-sided tape) under the insert to keep it from sliding around inside the tin. My initial version was meant to be a tight fit, but with how the bottom of the tin flares I was unable to get the tolerances perfect while still being able to actually insert the print into the tin.
