Richell Waku Waku Freezing Block Tray 80ml x 4 50ml x 1 25ml x 6 15ml x 2 Total: 13 pieces. One extra lid, usable for all sizes. Purchased at Akachan Honpo, Nishimatsuya, and Baby R Us. Purchase dates vary. Sterilized with Milton after each use, so there are water spots from drying. Used infrequently. I used the 25ml size often for things like omelets and steamed vegetable bread.
