METAura PRO with ergonomic design, a neck cooler with a cooling function. Operation has been confirmed. It seems useful for the coming season. The charging cable is missing, but it's a type-C cable, so you can charge it by purchasing one at a 100-yen shop or similar. The purchase date and frequency of use are unknown. There is some slight dirt on the case. The main unit has no scratches, cracks, or chips. Thank you for viewing.
