LCS17 觸覺板 Rough & Smooth Boards

Set of 3 boards 24 x 13 cm contrasting rough and smooth sandpaper in a wooden box. This set of three wooden rectangular boards aids in development of the tactile sense and preparation for handwriting skills. The first board has a smooth surface and a rough surface of equal size. The second board has a series of alternating rough and smooth strips to build dexterity and fine motor control. The third board has a series of sand gradations from fine to coarse. Our boards have the sand glued directly to the board, rather than using sandpaper cutouts, which can curl over time.
