This is an insulated lunch jar featuring the cute "Okame-chan" character. It's new and unused, but since it has been stored at home for a long time, I'm listing it as "like new." Includes the instruction manual and a matching color drawstring bag. No box. This is a non-sale item, won as a prize from Okame Natto. It states that it has a heat retention capacity of 43°C for 6 hours. Size: Approximately 19cm in height, 10cm in diameter at the base. Weight: 550.6g (including the drawstring bag and chopstick case) #NotForSaleLunchBox #NotForSaleInsulatedLunchJar #OkameNattoPrize #InsulatedLunchBox
