Crystal Steel Covers (for use with the Unibind )
The Unibind SteelCrystal are some of our most popular products. They are one-piece A4 covers made up of a U-shaped steel spine an acetate front and back, which are scored to lay flat.
The SteelCrystal is a clear plastic cover. A unique polymer within the u-shaped channel of the spine guarantees a secure and long-lasting bind but still allows your document to be edited.
Available in various sizes to hold up to 50mm.
