I bought this for around 6900 yen, but I'm selling it because the size didn't fit. I bought it to use with a trail running pack that wasn't Salomon, and I washed it once, but it didn't fit. I threw away the price tag and valve cover when I washed it. Please note that although it hasn't been used, it has been washed once. A lightweight and convenient set of two 500ml soft flasks. The cap for filling with drinks is a large type, making it easy to add beverages and ice. - Brand: SALOMON - Model: Soft Flask - Capacity: 500ml - Color: Blue - Quantity: Set of 2 Thank you for looking.
