Thank you for looking! ♪ This is a set of 2 glass storage containers. These were prepared as equipment for a rental studio. There are no instructions, so I don't know the product details (heat resistance temperature, dishwasher compatibility, etc.), but they seem to be usable in a microwave (as there is something like a steam vent for use). Since they are made of glass, they are less likely to retain odors and are relatively hygienic. The lids are the type that fasten on all four sides. Size (Large) Glass container: 20 x 15 x 6.5 cm (Small) Glass container: 11.5 x 11.5 x 5.5 cm How about this for those starting a new life, those considering replacements, or those who often prepare side dishes? I have another set of the same item. Please comment if you are interested. Returns are not accepted, so please contact me in the comment section before purchasing if you have any questions. The shipping method may change without notice. Please understand. Thank you. #sunny_outlet_shop #sunny_outlet_shop_zakka #sunny_outlet_shop_new_life_prep
