Doug's kit has 16" of duct tape. He protects the adhesive side by covering it with the waxy paper that backs address labels. I have found the 8.5" x 11" backing sheets for Avery labels in the office to be easy to collect in the office. One sheet is all you need.<br><br>Another trick to have tape at hand is to wrap a length around a plastic water bottle if you carry one. Then you don't have to open your PSK if you need a small length for a non-emergency situation.
