Universal stackable crates with signs and optional inlays

An universal set of crates of several sizes. These can be stacked together and have slots to add signs to know, whats inside.

If you want to design your own signs and keep up my design, use the font Arial Rounded MT Bold with a height of 6mm.
You'll also find covers for all sizes.
