I bought these before I realized it was so floppy and I still didn't know what it was for, haha, my daughter told me for ice. I guess you gotta really Love Legos to want 3 trays of Lego shaped ice cubes. i think its also silicone for making Varous chocolates, like a Chocolate mold and other desserts Perfect for a Birthday party, or just something to talk about Maybe make jello shots outta them? idk They are Branded Lego good quality, greay Condition. doubt they were ever used before. each tray makes 24 "cubes" but there's 2 sizes to it, lol, idk how to Explain it Deff a party convo!!
