Co-cos Shinoka Bolt Cool High-performance Peltier device GP-854, retail price 5480 yen. Purchased online from the official store and arrived on July 31, 2025. Used about 5 times, but I found the charging and setup troublesome, and I prefer to wear only an ice vest, so I'm selling this. The delivery details and the battery in the photo are not included. I am a non-smoker, but I have two cats, so please refrain from purchasing if you are concerned about allergies. To ship via Nekopos, I will disassemble it as shown in photo 3, fold the case, and wrap it in bubble wrap for packaging. Please understand.
