This fantastic tape is about twice as thick as masking tape, and at least twice as strong. The superior adhesive allows you to hang poster board and even cardboard to some of the most difficult surfaces, including drywall, plaster, brick, and even cinderblock! I know what you're thinking, "Won't a tape that strong take the paint off the walls when it's time to remove the posters?" Believe it or not, while the tape is heavy-duty, it removes easily from almost every surface (except lightweight paper.) With a little creativity, we're sure you'll find dozens of uses for this one-of-a-kind fastener. With two different sizes and five different colors to choose from, the sky's the limit. Once you try it, you'll agree, "It's mavalus, dahling, simply mavalus!"
