Vintage Tupperware Stackable Spice Containers

This vintage set of small Tupperware spice boxes was pretty well thought out: each box is independent but all are stackable.
 Their colors are rather nice. To use for your most common spices in the kitchen or to divert into pockets or boxes for buttons, sewing, paper clips, thumbtacks, etc.
 Dimensions: height of a box 6 cm, total height 21 cm, diameter 7 cm.
