Any art teacher can relate to this story. On a budget. Used my own money to buy the 6 pack so I could distribute among 6 work tables. Placed in heavy dispensers... ready to go? Not one of the rolls of tape worked properly the way Scotch brand works. Had to spend valuable time using my fingernails to unravel and cut into each roll until it worked properly in the dispenser while the students waited patiently. Next time I'll spring for Scotch brand.
