How many times have you put the tape dispenser down to grab something, pick the tape back up and the end had stuck to the roll. Ugh! Take an old credit card or hotel key, cut it 1/2 inches and use as a tongue to secure the tape from sticking to itself. You will be able to use the plastic tongue to pull the tape out easily.
My husband always put a penny at the end of his roll of tape. It works great!
