Place—and erase—game boundaries, agility courses, and more with special blue and green floor markers that easily wipe off with included wipes when the action dies down. Ink lays down clear, vivid lines that can be seen from afar and withstands foot traffic without fading or wearing off. Get creative using special marker tips that are capable of thick and thin lines. Ink supply lasts compares to five rolls of average foot tape. Use on any sealed wood or nonporous surfaces. Marker tip is 1¼"W.
