Fred M-Cups are modeled after the traditional Russian matryoshkas, so they stack and nest together for easy storage. You know cute isn’t enough at Kitchenette – we love these because they’re a hard-to-find set of 6, to accurately measure ¼, 1/3, ½, 2/3, ¾, and 1 full cup. No more double dipping for in-between amounts! Fred M-Cups are made from heavy-duty, food safe plastics and are packaged in an adorable gift box. No wonder they were our best-selling stocking stuffer last Christmas! Designed by Carl Mitsch. Hand washing is recommended.
