This is a set of five Richell freezing trays, each with a 15ml capacity, perfect for making and storing baby food in the early stages of weaning. Purchased new in June 2025 and used for approximately three months. Selling because my baby's needs have changed and I need larger storage capacity. There are no significant flaws, and the trays are still in good condition for use. There appears to be no discoloration. ●Product Information● Product Name: Wakewake Freezing Block Tray R 15 x 4 Size: 12.7 x 17.5 x 2.7H (cm) Capacity: 15mL x 12 blocks Material: Polypropylene Microwave defrosting: OK Dishwasher safe: OK Boiling, chemical solution, and microwave sterilization: OK
