The larger of this set of two pencil cases is made to sit on a desk, while the smaller is suited to travel. The exterior of the boxes are made of dark Walnut, which hides dirt and scuffs. The interior is made from birch allowing more light to reflect around the inside of box. The lids, made from sandblasted bronze, slide into a kerf which runs around the interior of the box. The under side of the lids are etched rulers.
