Richell Waku Waku Freezing Block Tray Used for storing baby food for 3 to 6 months. The number of lids is different. Tape was attached to the front of the lids to write the names of the ingredients, and there are about 10 pieces of that cellophane tape residue. I will include the trays I used (first image) and the new, unopened 25ml x 8 block tray (second image) ^_^
