※ Please also check my profile. Richell Waku Waku Freezing Block Tray This is a baby food freezing tray from Richell. It has been used, but it is still usable. I have thrown away the packaging, so I will send only the tray. 50ml x 2 15ml x 2 I used the 50ml tray to store vegetable sticks for babies to grab and eat.
