The Extenda-BondBlue Minis by Walker Tape are breathable and one of Walker Tapes longest-holding tapes. The distinctive holes allow the scalp to breathe, and the flexibility makes it extremely comfortable to wear. The tape has a very dull finish that is virtually invisible under the unit. Extenda-Bond Minis come in individual tabs on a blue liner. The tabs are 3/4 x 1 1/2 and come in 36-count bags.
