Using these Dragon Shield Dual Matte sleeves is easy. Just slide your card gently into the sleeve. It's important to handle the sleeves carefully to avoid any tears or scratches. When shuffling, you'll notice how smoothly they work. To keep them in good condition, store them in a cool, dry place away from direct sunlight. Avoid getting them wet as this could damage the material. If there's any dust on the sleeves, you can use a soft, dry cloth to gently wipe them clean.
