I purchased this last year and used it a few times, but I am selling it because I bought a different one. 【Functions】 Neck cooler with cooling and heating functions. - Brand: LaFuture - Model: Neck Cooler & Heater - Color: Night Navy - Temperature Settings: Cooling Mode: 25℃/20℃/15℃, Heating Mode: 39℃/42℃/45℃ 【Condition】 Operation confirmed. Cleaned with alcohol wipes. There are no noticeable scratches or stains, but there are some minor scuffs from use. Thank you.
