This is a set of 5 different-sized stocker cases, ranging from SS to LL. You can use them to store and keep various items and food for different purposes. They have a slide-out design for easy access (see images 6 and 7). As shown in image 1, all the smaller sizes can be stored inside the LL size. Sizes: SS…280ml S…440ml M…650ml L…950ml LL…1350ml These appear to be a prize of some kind, and have been stored in a kitchen cupboard for a long time. There are no noticeable scratches or stains. #stocker #storage box #food containers Thank you for looking.
