This elegant magnetic Bi-Office eraser has a sleek modern look due to its minimalist design and biocomposite material containing shell fibres. Biocomposites combine natural fibres with polymers, either synthetic or natural, creating materials with a distinctive appearance that are both resistant and durable. Make the board gleaming and ready to go in just a few minutes and clean any large or small dry erase whiteboard in the office, classroom, or at home. This eraser wipes the ink away easily and doesn't leave any smears, even if the ink has been on the board for several days. No need for sprays or cleaners. Just stick it to magnetic whiteboards, fridges, combination notice boards, and weekly planning boards for quick access and easy storage.
