Our Erasers Puffs make erasing fun! Made from microfiber, the Eraser Puffs are great for thoroughly cleaning dry erase surfaces. The elastic band included on the eraser makes it easy to secure the eraser to your hand for quick erasing. It’s great for young children who are trying to hold a dry erase lapboard and an eraser in their helper hand while writing on the board, making it easier for them to erase in between activities. The 3" x 3" erasers are also easy to clean in between uses. Each package contains 5 Eraser Puffs in 5 assorted colors: Red, Yellow, Green, Blu,e and Purple.
