Thank you for viewing. This is a set of 4 OXO Pop Containers. The lids are stainless steel. Size: 0.3L. Approximately 10.5cm x 10.5cm (width and length) x 8cm (height). Purchased about 10 years ago and used for about 1-2 years. After that, they were disassembled, washed, and stored in a dark place. Although they have been washed, they seem to retain a slight aroma of seasonings, as they were mainly used for things like dashi granules. There are also some minor scratches from use. For those who don't mind. *Based on the photos, the lid shape seems to be different from the current product. Please be aware of this. No pets or smokers. OXO Silver Stainless steel
