These products are still in good condition and still usable/functional. Due to the unique nature of these deals we cannot accept returns of these items and would not be able to replace them. Printed on one side with centimeter scale. Essential whenever you use rotary cutters; they are soft enough to protect the blade and hard enough to prevent deep incisions.
