Abstract

The invention under scrutiny focuses on a white board eraser (1), which comprises a central core (2) and a stack of eraser sheets (3) arranged together with the central core (2). The central core (2) has been made into the shape of a rectangular piece, which has two ends (2p1, 2p2) and four sides (2s1-2s4). The surface area of the ends (2p1, 2p2) does not in principle exceed that of the sides (2s1-2s2). The central core (2) of the white board eraser (1) has been made into a boxlike structure. The said stack of eraser sheets (3) has been wrapped round the central core (2) covering at least three of the sides (2s1-2s4).
