New, unopened packaging around the mouth. SALOMON soft flasks. Two 500ml flasks, unused. - Brand: SALOMON - Color: Blue - Quantity: 2 - Capacity: Approximately 500ml Thank you for viewing. These came with the hydration pack ADV HYDRA VEST 4. I am selling them because I don't use them. One of the two flasks has a faint shadow. (See photos 3 and 4) I tried wiping it with alcohol, thinking it might be mold, but it didn't feel like it and wouldn't come off. By the way, there is no lie in the fact that they are unused, and I have never put any liquid in them. I will discount them accordingly.
