Although unused, I connected the battery to check the cooling function, so I confirmed its operation. Therefore, it goes against the description of "new and unused," so I've classified it as "like new." As described, it cooled down immediately. It has excellent functionality, so if I can't sell it, I'll keep it for myself. A USB-rechargeable neck cooler in black, capable of cooling to -17°C below the ambient temperature. Cools in 2 seconds, a next-generation cooler Up to 2 hours of use Keeps you cool even in the blazing sun It also has a "fluctuation mode" so it doesn't get too cold, allowing for comfortable use for extended periods. This item was not brought by a family member who transferred. Although unused, it has been powered on once to confirm its operation. It certainly cooled down in two seconds. - Product Name: NECK COOLER Slim - Cooling Temperature: -17°C from ambient temperature - Cooling System: Small cooling plate - Power: USB rechargeable - Battery: Included battery can be used [No box] Accessories: Lightweight battery USB cable Instruction manual I plan to take it out of the paper box and ship it as shown in photo 9.
