I debated long and hard, just about the size needed for storage and buying a rather expensive (for me) pop-up tool. I was so glad I made the purchase, and continue to be pleased with the results. No waffled attachments, like with small round or square dots; easily sizable strips for the exact measurement needed; and a stick-ability that continues to last on the roll and on the card - no deterioration. I will definitely purchase this item again when needed. 3M continues to live up to its reputation for good quality products at a reasonable cost.
