The bane of existence for many trading card collectors is having one of their prized possessions bent. While some types of physical bending damage to cards can't be truly undone, sometimes cards become bent or warped due dry air, as well as humidity. Dedicated card collectors often keep their collections in conditions where temperature is controlled, but it can be hard to maintain completely, especially when using the cards in play.

Japanese Twitter user Tetora (@tetorasan2021) recently delighted many not quite sure how to address the upkeep of their bent cards with a simple DIY fix. Out side of your bent cards, you only need less than a handful of everyday household items.

Tetora first explained on how to easily unbend your cards when they have a crease that bends upwards like a mountain.

Tetora provided a simple picture guide to demonstrate as well.

Take your bent cards

Place them in Tupperware next to a wet tissue or sponge (make sure the cards don't get wet)

Wait about a day and voila!

For when cards are bent inversely or downwards, Tetora says to simply replaced the wet tissue with a desiccant or drying agent package to fix the bend the other way.

While many card collectors probably do their routine best to keep their collection in mint condition, this looks like a very simple and quick trick to getting your bent cards back on the mend!
