Choose from three sizes. The 2-Row case holds up to 60 slabs for a focused Mariners collection. The Slab Case X holds up to 110 slabs for larger team sets, and the XL offers plenty of room as your collection keeps growing. The carbon-fiber-style foam fits PSA, BGS, SGC, CGC, MagPro, and One Touch holders. Every case includes a built-in lock and two keys, keeping your Seattle cards secure at home, on the road, or at your next card show.
Whether you're holding classic Mariners rookies, fan-favorite veterans, or the team's newest stars, your slabs need more than a drawer or a box. Our graded card cases give each slab its own foam slot, holding it upright and separated so holders don't scrape or crack. Your collection stays organized, and finding a specific card for a trade or display is quick and easy.
