Used only once each. I'm selling these because I don't think I'll have much opportunity to use them. This is the price for all 5. 【Like freshly cooked rice】Developed in collaboration with rice experts. A small size has been added to the "Goku Frozen Rice Container," which was developed to allow you to enjoy the deliciousness of freshly cooked rice even when frozen. Focusing on delicious "thawing," we have perfected a shape that allows you to heat rice evenly and fluffily in the microwave. You can heat it with the lid on. 【Removes excess moisture and prevents sticky rice】The slatted part allows excess moisture to drain, preventing the rice from becoming sticky. Simple design with no corners or indentations. Easy to clean with few parts. The slatted bottom part can also be removed and washed. *Dishwasher safe 【Space-saving simple design】Stackable for compact storage in the freezer. One container can freeze a small amount (about 100g) of freshly cooked rice. Because of its simple design, you can use it as is on the table or as a rice container for your lunch box without any problem.
