The FloormarX® H2O Floor Marker is rugged for long-lasting durability. This extra-large marker writes on sealed wood floors and other non-porous surfaces. The ink can stand up to heavy foot traffic, and then be cleaned off most sealed floors with FloormarX® R&R Foot Towels and water. Use FloormarX Foot Wipes for hard to clean floors or for ghosting. The large ink supply will last as long as five rolls of average floor tape. One Single Orange Marker
