In need of the perfect companion for your dry erase markers? Arteza's magnetic whiteboard erasers are the perfect fit! These two toned foam whiteboard erasers come in a pack of 20, and are ideal for office, school, or home use. They are magnetic, so they are always right where you need them - on the whiteboard. Their small square design measuring at 2x2 inches keeps them from taking up precious writable space, and allows them to be tucked into the corners of your board. The erasers wipe clean and remove marker ink from any non-porous surface you may have--from the standard large classroom whiteboard to small calendars and memo boards. Students and teachers love them, but they're also a perfect fit for the office or even at home. They are made of highly durable materials and wash clean with mild soap and warm water. These erasers are a must for all your whiteboard needs.
