This is a set of four Nitori airtight, heat-resistant glass food storage containers. The rubber-sealed lids are stiff, and my elderly mother finds them difficult to close, so she rarely uses them. I am selling them. The set includes sizes from large to small. None of them have any cracks or chips. Sizes ① to ③ are listed on the official website, so please refer to the photos. The sizes appear to be the dimensions with the lid and seal closed. The smallest size, ④, is not listed on the Nitori official website. It is likely discontinued. I remember ④ having a capacity of about 180 milliliters. It's perfect for storing small amounts of kimchi or pickles. Even I find the rubber seals stiff. If you are interested in using the heat-resistant glass containers primarily, please consider purchasing them. I am looking forward to your purchase if you understand that these are used items. - Material: Glass - Lid Material: Plastic - Quantity: Set of 4 - Features: Airtight
