【Brand】WECK 【Material】Plastic 【Size】 S: Approximately 7cm in diameter L: Approximately 11cm in diameter 【Heat Resistance】80 degrees Celsius I mostly use the glass lids, so I haven't used these much and am putting them up for sale. I think they are in good condition, but they have been stored at home for a long time, so I recommend them to those who don't mind.
