I needed tape to seal "custom" odd-sized envelope/packs that contain books and magazines that I mail. I had been using "US Postal Service Approved" Scotch brand tape. I wanted a cheaper alternative that would endure anything the postal service could do and protect the contents. I found this tape to be lighter very easy to work with very adherent and smooth and was a great replacement for the more expensive and slightly thicker brandname product. It fits the standard handled dispensers so it could be used with boxes as well but that's not my primary use. VERY pleased.
