New, unused. I purchased these online, and I'm using two at home. I intended to use all of them, so I don't have the packaging. Microwave safe (heat resistant to 120°C, cold resistant to -20°C). Size: Approximately 10cm long, 15.5cm wide, 6cm high. At home, I use them for lunch boxes and for storing prepared foods. (Note) These are not airtight. Please understand that these have been stored at home before purchasing.
