I've taken up restoring Pokémon cards as a side hobby. Fixing dents, scratches, flipped corners, etc., I have pretty much down. The last thing left to master is minimizing and/or eliminating creases.
You can minimize the appearance of creases. Some can even be eliminated. Others can't be eliminated completely, but you can make them much less noticeable with the right tools.
This is one of them.
It's basically a facial massage roller but it can be used to smoothe out creases in cards. You can get these on Amazon for $8-10.
A few websites dedicated to restoring Pokémon cards sell these for... $22. Here's their version.
There's obviously a slight difference in the thickness of the larger roller, but not enough to make any sort of significant difference. Yet they're charging nearly triple the price of what you can get it for on Amazon. It definitely pays to shop around so you don't get taken for a ride.
