{"product_id":"inner-card-sleeve","title":"Inner Card Sleeves","description":"\u003cp\u003eDouble-sleeving isn’t excessive - it’s the industry standard for valuable cards. Our Inner Card Sleeves fit standard-size cards with micron-level precision, sealing out humidity, fingerprints, and micro-dust before the outer sleeve ever comes into contact with them. The 40 µm high-tension film is optically pure and adds negligible thickness, meaning that stacks remain tournament-legal and binder pages lie flat. The low-friction interior glides over holo surfaces instead of scuffing them. Each sleeve is ultrasonically sealed on three sides for maximum structural integrity, and the open top allows for faster insertion and smoother nesting inside Grade Saver Pro Base Sleeves or Pull Tab Sleeves. Like every product in our range, these inner sleeves are laboratory-verified as being acid-, PVC- and lignin-free. When perfectionists talk about a ‘perfect fit’, this is what they mean.\u003c\/p\u003e","brand":"Grade Saver Pro","offers":[{"title":"100 pcs.","offer_id":53949003006279,"sku":"88604","price":3.49,"currency_code":"EUR","in_stock":true},{"title":"200 pcs.","offer_id":53949003039047,"sku":"88605","price":6.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/0258\/3367\/files\/01_inner_sleeve_saverpro_square.jpg?v=1785145534","url":"https:\/\/saverpro.com\/products\/inner-card-sleeve","provider":"Saver Pro","version":"1.0","type":"link"}
