Used only once each. I'm selling these because I don't think I'll have much use for them. This is the price for all 10. 【For Delicious Rice Like It's Just Cooked】Developed in collaboration with rice experts. The "Goku Frozen Rice Container" was created to allow you to enjoy the deliciousness of freshly cooked rice even after freezing, and now a small portion size is available. Focusing on delicious "thawing," we have perfected a shape that allows for even and fluffy heating in the microwave. You can heat it with the lid on. 【Excess Moisture is Removed, Preventing Sticky Rice】The slatted part allows excess moisture to drain, preventing the rice from becoming sticky. The design is simple, with no corners or indentations. With few parts, it's easy to clean. The slatted bottom part can also be removed and washed. *Dishwasher safe 【Unobtrusive Simple Design】They can be stacked, so they don't take up much space and can be stored neatly in the freezer. One container can freeze a small portion (about 100g) of freshly cooked rice. Because of the simple design, you can use it directly on the table or as a rice container for your lunch box without any problem.
