Product Name: Sawyer SAWYER Mini MINI SP128 [Outdoor Water Filter] Although unused, I have taken it out of the box and carried it once. I purchased it from the Yodobashi website last year as insurance in case of emergencies during a long mountain climb without a water source, and I carried it with me. I only carried it once at that time. Although unused, I took it out of the plastic case to carry it. I put it in a separate bag when I carried it. I will ship it in the original case as shown in photo 1. Although unused, it is a pre-owned item that has been opened.
