Instant ICE STAMP - Approx. 250 uses per stamp - 2 stamps (1 is partially used)

Two seasons ago, I used to stamp these cooling towels and wear them around my neck, but last season, the cooling towels alone were sufficient, so they didn't get used. I'm offering these to anyone who wants to try them out or keep them as a backup. One towel is unused, and the other is about half-used. If you have a budget in mind, please let me know. I'm willing to negotiate.
