Hello! (^○^) This is a triangular onigiri (rice ball) case with a cute Snoopy design and a cooling function. (GEL-COOL Triangle Case) ----- This case has an integrated cooling pack. Freeze the cooling lid overnight in the freezer for use. Provides peace of mind with cooling in the summer heat and the winter heating. Guideline for maintaining cooling effect (below 15°C) at an outside temperature of 25°C: → Approximately 4 hours * When food (5°C) cooled in the refrigerator is placed inside. Cooling effect is further enhanced by placing it in a cooler bag. ----- This item was included in this year's PEANUTS Cafe lucky bag, but I haven't used it, so I'm putting it up for sale. The length of one side of the triangle is approximately 10 cm, and the thickness is approximately 6.5 cm. Instant purchase is also possible, but feel free to comment if you have any questions or if you'd like to combine shipping! However, please note the following points before purchasing: ・Stored at home (No pets, no smokers) ・Simple packaging ・Anonymous shipping (Shipping method will be determined by me) Please consider purchasing only if you understand all of the above.
