I might have to splurge on this one: nesting doll measuring cups. They are a set of 6 dry-measure cups shaped and nests like matryoshkas or Russian nesting dolls. Sizes: 1/4, 1/3, 1/2, 2/3, 3/4 and 1 full cup.
The trouble is, this store is sold out of the measuring cups until January. They were charging $11.95 for the set. Other stores were charging as much as $16 for the same thing, so I think I’ll wait until they are back in stock.
