storage.boutique has developed an innovative new, Acid Free, lightweight three layer, archive sleeve specifically sized for Starbucks gift cards. These are ideal for Starbucks collectors. Our sleeves retain crystal clear transparency and have no hard perforated plastic edge to detract from the display, dull, or scratch. Our storage.boutique sleeves are made from a triple layer which protects the cards from the damage caused by ultraviolet light, acid and moisture.
