Tough and durable, this premium two-inch wide fabric tape from the "Bookguard" brand is a hefty 13-mils thick, which makes it substantially strong with a 45 pounds-per-inch tensile strength. The tape has a matte finish, and it's made of cotton cloth with a vinyl coating. Its high resistance to abrasion and abuse (due to its high thread count) over time ensures that it wont crack or easily fall apart - there's a reason "Bookguard" has been a favorite book-binding tape for more than 30 years! The cloth material of the tape is highly-conformable to most surfaces, and you can easily write on the tape's surface with a felt-tip marker. Its ultra-aggressive adhesive permanently adheres to the most difficult surfaces, including vinyl. Each finished roll of "Bookguard Premium-Cloth Book Repair Tape" is cleanly shrink wrapped before shipping.
