How should I store my MTG cards to keep them in good condition?

To keep your Magic: The Gathering cards in good condition, store them in protective sleeves or binders to prevent wear and tear. Keep them in a cool, dry place away from direct sunlight and moisture. Avoid bending or folding the cards, and handle them with clean hands to prevent oils and dirt from damaging them. Regularly check and organize your collection to ensure they stay in good condition.
