How do you keep foil Magic cards from bending?

Moisture causes them to curl. Physically bending them isn’t the best idea, as they tend to go back to curled faster vs actually drying them out and then double sleeving them. Buy some silica gel packets or beads (preferred, as they are easier to recharge), then stick them into an air tight container with the cards.

How do you flatten a curved foil card?

To uncurl most foil Magic cards you’ll need to raise the moisture of the card which you can do in a homemade “hydration chamber”. The technique is straightforward: create a small space with high humidity to rehydrate the card, remove it, then flatten it overnight to reshape it.

What causes foil cards to warp?

Warping. Foil Magic cards are made of two things — cardboard and metal foil. If you store your cards in a very humid environment, the cards will curl with the backside of the card bulging out because the backside of the card has room to expand while the front half is fixed in place by the foil layer.

Why are my Magic cards bending?

Basically it’s an issue in how it’s made, the foil layer tends to bend as it pulls moisture out of the air. If *all* your foils are bending, you’re likely storing them in a room that’s too humid, and might consider purchasing a dehumidifier.

Do foil etched cards curl?

If the temperature and humidity are at the temperature the cards were printed at, they won’t curl. If you keep your cards in a super dry environment and under a lot of heat, you are going to get extreme curling. Foil-etched cards warp less than traditional foils.

Do etched foils curl?

If the temperature and humidity are at the temperature the cards were printed at, they won’t curl. Foil-etched cards warp less than traditional foils.

Why are my cards curling?

Humidity (moisture in the air) is the biggest reason why foil cards curl. Since the front of the Magic card is made from mylar, it won’t expand or contract when exposed to the moisture in the air. This causes the edges to curl toward the cardboard backing of the card.

Why do foil Magic cards curl?

Does double sleeving prevent warping?

While single sleeving protects against general wear and tear, double sleeving makes your cards waterproof and nigh-indestructible. Double sleeving is also better for foils since it reduces the air flow around the card and helps prevent warping.
