There are a number of ways to protect your cards from damage. One popular method is to use a screw down card holder.

Like all of the best protection methods these are from Ultra Pro and they are popular because they do such an excellent job of protecting your valuable cards.

From as little as $2.50 per screw down they are an excellent item to have in your collection.

They are made of a clear rigid-plastic and have either one or up to four small screws holding the 2 piece holder together. Most screw downs have a recessed area to fit the card so that the card isn’t squashed between the two pieces of plastic — instead it merely sits between the two halves in the recessed area.

The screwdowns make it virtually impossible for your card to be creased or folded, and it protects the sides and corners from damage. Being clear they still allow you to view both sides of your card so you retain maximum visibility.

The screw downs are acid free and contain absolutely no PVC, which is important for collectors because it means your cards will be protected for many years to come.

Acid and PVC can leach into your cards, making them fade, stick to the page and be quickly destroyed. Beware of cheap imitations, and trust in the Ultra Pro brand.
