Serious about protecting your valuable Magic: The Gathering, Pokemon, or other trading cards? Dragon Shield Inner Sleeves are a must. This pack gives you 100 clear, sideloading inner sleeves. They're made from archival-safe, PVC-free polypropylene that's 40 microns thick – that's the perfect balance of being thin enough to not bulk up your deck too much, but strong enough to shield your cards from dust, moisture, and minor scratches. The 'sideloader' design means you slide the card in from the side (not the top), which can sometimes offer a slightly tighter fit and easier insertion. These are designed to hold cards up to 63x88 mm (the standard 2.5\ x 3.5\ size). The best practice? Put your card in one of these inner sleeves FIRST, then slide that into a regular Dragon Shield outer sleeve (or any standard-size sleeve) for double protection – that's called 'double-sleeving' and it's the gold standard for keeping cards in mint condition. Acid-free and safe for long-term storage. Whether you're a tournament player or a collector, these inner sleeves are a small investment to keep your cards looking fresh. One sealed pack, 100 sleeves total.
