storage.boutique has developed an innovative, lightweight, triple layer archive sleeve specifically sized for Cabinet cards. These are ideal for Cabinet card collectors. As you would expect, all storage.boutique sleeves are acid free. In addition, our sleeves are coated on the outside layer of the three layer film to retard the harmful effect of ultraviolet light. The middle layer is a dense core giving strength which prevents tearing. The inside layer of our sleeve is made from an untreated material which ensures that the sleeves are completely acid free on contact with your precious collectible. Our sleeves are sealed at the edge by compression and ultrasound, meaning that there is no hard plastic serrated edge. Our sleeves will fit neatly around your collectable, putting the focus on the contents. Unlike hard plastic archive sleeves, the new technology material does not dull or scratch over time and retains the crystal clear transparency that you want for your collection. If you are an experienced collector, you will know how putting a document into a hard plastic sleeve can bend or dent your collectible. That’s not the case with storage.boutique sleeves, as ours are made from a soft but dense lightweight material deliberately designed to prevent such a calamity.
