Thank you for viewing! This is a large-capacity 1.5L stainless steel bottle, a 2-way type water bottle with a straw and direct-drinking option. It has a vacuum-insulated double-wall structure, keeping drinks HOT for about 12 hours and COOL for 24 hours. Although it is unused, there may be some scratches on the box. We would appreciate your understanding in this regard. Please feel free to contact us if you have any questions.
