TeachersTape Double-Sided Removable Foam Tape Pads is a removable foam tape that comes off cleanly with no adhesive residue or tape scraps. This is a great alternative for masking tape, mounting clay, push pins and other more expensive fastening options. Each pad contains 8 3/4-inch x 3/4-inch pieces. Note that the TeachersTape is sold as either a full-length roll (2,000 pads per roll or 16,000 3/4-inch x 3/4-inch pieces) or 8 pads per pack (64 3/4-inch x 3/4-inch pieces) The tape works well with surfaces found and around the classroom such as painted concrete walls, chalkboards, whiteboards, wood, metal, plastic and glass.
