Purchased in November 2023 at Kojitsu Sanso for mountain climbing. There are no noticeable scratches or stains on the exterior. Although it is unused, I am listing it as "like new" because I carried it for mountain climbing (it has never been sprayed). It provides peace of mind, especially for dealing with the end of hibernation in early spring, and when carried while mountain climbing. Expiration date: December 2026. *To prevent any issues, returns and cancellations are not accepted.
