Knives Out Arashi Peninsula Design Water Bottle Color: Black Height: Approximately 20cm Unused, stored item. When listing, I removed the lid to check the inside. A paper with pre-use instructions was inside. I am unsure of the material or capacity details, but I believe it is made of stainless steel with thermal insulation and cooling functions. The capacity is estimated to be around 300ml, but it is unconfirmed. There was a time when it was displayed outside of the plastic bag, and there are some scratches on the bottom. Please check the photos and consider purchasing.
