To store things neatly in a manner that allows them to be taken out easily by combining partitions made of a synthetic resin, on both sides of which rails and grooves are molded at a prescribed interval, into squares in accordance with things required to be stored.

Partitions 3 are made by molding a synthetic resin such as styrene into plates with a width suited to the depth of a drawer 2 and providing rails 5 and grooves 6 at a prescribed interval on used surfaces. Such partitions 3 are given a prescribed length and combined into squares and stored in the inside space of the drawer 2. That is, a groove 6 of one partition 3 and the edge 7 of the other partition 3 are molded in the same shape, respectively and fitted to each other, and the interior of the drawer 2 is divided by cutting one edge side of the groove 6 straight and by butting the end face of the edge 7 against the bottom of the groove 6 in the form of a plane when they are fitted to each other, thereby storing things neatly in a manner that allow them to be taken out easily.
