The sponge impresses with its robust design and guarantees reliable, residue-free daily cleaning. Thanks to the magnetic self-adhesion on metal surfaces, the wiping sponge is always ready to hand, does not get lost and does not require a separate storage surface. The felt side of the eraser sponge removes whiteboard marker notes precisely, effortlessly and without smearing, even on large surfaces. Hands remain 100% clean. Thanks to its ergonomic shape, the sponge is easy to grip, fits in any hand and makes it easy to use for quickly erasing whiteboard notes and drawings. Sponge size: 10.5 x 5.5 x 1.8 cm. Brings colorful accents to classrooms, offices, workplaces, meeting and seminar rooms or even in the home. Available in yellow, green, red and blue with an attractive design.
