Nine sets of frozen baby food block trays, a container for powdered milk for travel, and three nipple brushes for baby bottles. The items taken out of the bags are also unused. I'm not good at cooking, so I only made pouches and simple things, so I didn't use these. The yellow and yellow-green trays are silicone and can withstand temperatures from 120°C to -20°C. I have siblings and often visited my parents' house, so I bought a lot of these. I think they are convenient for making a large amount of food when you have time. Please understand that these items have been handled by someone else.
