I use it for a few different purposes the first obvioulsy for sealing packages via USPS. Other packing tape is thin flimsy and not sticky enough. I was introduced to this tape by a Librarian when it was called "Book Tape". I use it for business personal and teaching purposes. I use it to laminate small objects (handmade bookmarks business cards etc.). It's a thick crystal clear tape that's durable unlike packing tape which can be hazy. I love that it is wide 3" because it fits most arts and crafts projects. I use it when I teach duct tape art projects because its quality can handle the different purposes the students ask of it and is on the same level as duct tape. One roll lasts a long time about a year so I wish it was sold in smaller quantities.
I needed to use the tape instead of a laminator to cover items that can be ruined by moisture. This tape worked perfect and I didn't have to buy a case of them!
