9 ¹³/₁₆" x 20 ³/₈" Adjustable Book Cover (25/Pk)

These Slip-On Book Covers will easily slip-on to your soft cover books to help protect the delicate paper covers from bending and tearing. These plastic book covers are easy to adjust to most book widths for the perfect fit, as the sides fold over and are inserted into a "holding" strip. The one-piece 7 mil thick vinyl is heavy duty and durable. These reusable book covers have no adhesive and will not cause damage to the book itself.
