Uses: Compatible with microwave ovens, ovens, and dishwashers, allowing for a wide range of uses from cooking to serving at the table. Sizes: Available in three sizes: 900ml, 1500ml, and 2200ml, and can be nested for storage. Hygiene: Resistant to odors and color transfer, making them hygienic. This is a new, unused item, but the box has some discoloration. Please understand that this item has been stored at home. #glassbowl
