Stick EZ pads are self-adhesive pads. No need to mess with removing a strip from the back to make these sheets stick, just peel off pad and stick to a smooth surface. Made from a heavy weight paper with a chipboard backing and glued at the top. Micro perforated for easy tear off and three hole punched to fit all standard easel stands. Pads work well with Flip Chart, Dry Erase or Mr Sketch markers. Not suitable with Permanent Markers, Water Colors or Paint.
