No price reduction, immediate purchase is welcome. I don't have any pets, and I don't smoke. ● Simply heat it in the microwave to provide a comfortable warmth, warming cold feet. ● Large L size (twice the size *compared to Hakugen Earth Co.), so it can warm a wide area inside the futon. ● It's a soft and comfortable gel-type hot water bottle. ● Warmth lasts for about 7 hours.
