I am forever searching for these--hard to find, it's a very happy day when I do, and whenever I list a set they are usually the first thing sold. The paint and the wear is important though--the paint on earlier sets like this softens and wears away, rather than chips off--I'll never buy a set where the latter is the case! It is possible this set once included a larger red box, but there's five now, with the orange the largest. Jointed corners, great general wear, especially lovely along the top edges as shown when they're all nested. I could spend hours arranging these in different configurations--like tabletop Stella's and Rothkos. Yum.

Largest 5 1/16" x 5" x 4 3/4". All in great, well used condition, sturdy and sound, perfect patina.
