Write-on/cling-on easel pads feature poly sheets that cling to walls, cling to each other and cling to most dry surfaces by static electricity. No tape, tacks or adhesive are needed. Reusable sheets wipe clean when using dry-erase markers. Or use permanent markers to save notes. Each write-on/cling-on easel pad fits a standard flip chart easel or conference cabinet. Rolls up for travel or storage. White perforated sheets tear off cleanly. 35 sheets per pad.
