Thank you for viewing! This is a stainless steel bottle (dark blue, approximately 280ml capacity) from the outdoor brand "PRO TREK". It comes with a box and is brand new, unused. The simple and high-quality design is recommended for outdoor activities such as mountain climbing, hiking, and camping, as well as for everyday use, work, or school. It supports both cold and hot beverages. 【Product Information】 ・Brand: PRO TREK ・Capacity: Approximately 350ml (estimated) ・Color: Dark Blue ・Material: Stainless Steel ・Condition: Brand new, unused (with box) This was received as a commemorative item for an event, but I am selling it because it has been stored unused. Please note that I did put water in the bottle once to check if it could keep things cold. Please be aware that this is not a cold-retention bottle. I am also selling other outdoor goods. If you are interested in purchasing multiple items, I will consider a discount, so please feel free to comment.
