The Tombow MONO Dust Catch eraser features a tacky polymer formula that collects residue, preventing it from scattering over your drawings and artwork. This eraser comes in a protective sleeve and measures 65mm x 16mm x 7mm. It offers residue-free erasing without damaging your artwork, as eraser bits stick to the eraser itself. Made from PVC, it is phthalate-free and latex-free, weighing 19g.
