♢ Antibacterial Small Portion Freezer Tray 15ml x 12 blocks x 4 pieces ♢ Antibacterial Small Portion Freezer Tray 25ml x 8 blocks x 4 pieces This is a set of 8, with 4 packs of each of the above 2 types. Used when making baby food, and stored after washing. I stopped using them as the amount I was eating increased. The 15ml tray was used about 4 or 5 times, and the 25ml tray was used about 2 or 3 times. There are slight indentations, but they are in a condition that can be used without any particular problems. There are no stains or discoloration, and I think they are relatively clean. Since they are not unused items, please refrain from purchasing if you are concerned.
