These items were washed and stored with the intention of being used. Since they were washed but never used, they are practically new. I had planned to use them, so I disposed of the box, etc. I also removed the strap, as I didn't plan to use it, and stored it separately. I looked for it, but couldn't find it, so I assume I threw it away. I'm selling this because 1.5 liters is too much for me, and I haven't had a chance to use it.
