I use the "Really Useful" boxes in many sizes, this is my preferred size. Perfect for storage of small items for it all. The well stackable boxes are durable, also the mechanics. Probably the best product of its kind on the European market.
It lacks a slot for the label. Unfortunately, full point deduction for the very high price (~ 22 DM). Shape or color of the plastic I have so far (2 years) can not be determined.
