Thank you for viewing! #soranoao's products are here *Please note that there are no tags as this product is made overseas. This is a large-capacity 2000ml hot water bottle. It has excellent heat retention and keeps you warm, making you feel good♪ I myself used the 1000ml size on my lower back, and the moderate warmth was very pleasant and lasted a long time. It was essential and indispensable during the times I had lower back pain(^^) *There's no need to worry about leaks if you close the lid tightly! Size: The hot water bottle on the right side of photo ⑦. Material: Polyvinyl chloride This hot water bottle is a favorite of mine, with its lovely pink color and the feel of fleece material♡ Disposable heat packs are good, but traditional hot water bottles are also great♪(*^^)
