This is a set of four Richell Wakewake Freezing Block Trays. They are convenient for making and storing food, as you can take out one block at a time. I've used other brands, but Richell's freezing trays are easy to remove food from, no matter what you put in them, and I recommend them. They come with lids and can be stacked for storage. They have been washed, but please note that they are used items and may have minor scratches. Please see the photos for the condition. ▼ Set Contents 15ml x 2 25ml x 4 All with lids Material: Polypropylene Microwave safe Dishwasher safe Boiling and chemical disinfection OK *From the product site - Features: With lids, stackable Baby food storage container Richell Richell Baby
