Scotch Heavy-duty Shipping Packaging Tape raises breast cancer awareness with its pink dispenser. A portion of the proceeds is donated to the nonprofit City of Hope to fund research, education and treatment. 3 mil thick tape is 20 times stronger than acrylic tapes, seals seams with one strip and keeps boxes closed. Tape also resists slivering, splitting, and tearing. Ideal for shipping heavy packages or moving needs, such as packing boxes in the office. Tape meets U.S. Postal Regulations for standard packages.
