STAINLESS ONE TOUCH BOTTLE 520ML WH

It has a large capacity and is light, so I use it every day at work, filling it with iced barley tea in the summer and hot hojicha tea in the winter. I made a big mistake once when I absentmindedly put a bottle of hot tea into my backpack and took a few steps before I realized I'd forgotten to put the rubber seal in. Everyone, please make sure to put the rubber seal on tightly after washing the bottle!
