I purchased this item on Mercari, where it had been used a few times. I've used it for 4 months, less than 10 times total. The instruction manual is not included. I used it by referring to the instructions on the official website. This is a 9-in-1 hot and cold facial device. It provides comprehensive skincare with hot and cold care, EMS, light therapy, ion cleansing, and ion moisture. This ANLAN facial device allows for mode switching and level adjustment. - Brand: ANLAN - Model: Facial Device - Included: Charging cable
