These are akin to the wooden nesting boxes painted in primary colors I am forever looking for, but blocks instead of vessels, and with beads of various sizes inside, giving each one a different sort of rattle. Good stacked into modernist formations, or used as pedestals for other things, or just tossed around.
2 13/16 cubed. Set of five. General wear with a little paint loss here and there, all very sound and sturdy.
