LOTTE Koala's March ✖️ Hokaron ○ Personal Cold Weather Gear ○ This is a soft fleece microwaveable hot water bottle cover ☺︎ The microwaveable hot water bottle has hardened somewhat due to age. I tried using it, and it did get warm, but there may be safety issues, so this listing is only for the Koala's March cover. How about using it with your own hot water bottle? A Koala's March strap is included as a bonus. - Material: Soft fleece material 　　　Polyester 100% - Size: Approximately 28cm x 20-23cm (Zipper opening 22cm) This is a used item, so there is some wear and tear and some stains. (Please check images 7 and 8) Please feel free to comment if you have any questions. * We do not accept returns. Thank you for looking. #Koala'sMarch #LOTTE #Hokaron #WinterGear #ColdWeatherGear #SleepWellGear #HotWaterBottle #BodyWarmer #ColdRemedy #PersonalColdWeatherGear
