BIC - BICGDEM11GN Intensity Low Odor Dry Erase Markers feature a versatile chisel tip for both broad strokes and fine lines. Low-odor ink doesn't leave behind a strong smell so you can feel good using them in your classroom or office. They also erase easily and cleanly from dry-erase boards for a clean slate as you teach, plan, brainstorm or strategize. ACMI-approved, nontoxic markers provide smooth ink flow and bright, low-odor ink. They are suitable for use on dry-erase boards, glass and most nonporous surfaces.
