PURPOSE: To provide an article storage tool capable of individually storing gems, easily visible from the outside, easy to handle, and capable of effectively utilizing the space of a main body by using transparent belt-like sheet materials, forming the upper edges and lower edges into a corrugated shape, fixing them to the main body, and providing small-partition pockets.

CONSTITUTION: Pocket sheets 1c are closely stuck to a main body 2 and fixed at fitting line sections S1, pocket ports 14 are formed in partitions between vertexes 13, and pockets 10 are arranged in a zigzag pattern so that gems can be individually stored and the main body 2 can be suspended and folded.
