When your product requires thousands of easy openings and secure closings, eliminate the work and weight of metal closures and choose 3M™ Hook and Loop Fasteners. Fastener consists of two woven strips, one covered with stiff hooks, the other with pliable loops. Press together to fasten; pull apart to separate. Open and close up to 5,000 times. Available with pressure-sensitive adhesive backing or plain backing for sewing or stapling.
