This is the original Aqua Esthe Sonic, which features a massage function using sonic vibrations. I purchased it at Yodobashi Camera several years ago. I used it about 3-4 times, but honestly, I didn't feel much effect on my skin, so this item has been sitting in my closet. I'm looking to sell it at a reduced price during the Golden Week decluttering. I haven't used it much, so there is no damage or dirt on the main unit, but since I bought it many years ago and it's been stored in the closet, the outer box and instruction manual have some age-related discoloration. I'm pricing it low, hoping to at least cover the shipping costs. The operation has been confirmed. It works perfectly fine. Please check the photos to confirm the condition and make your own judgment, and purchase with no claims and no returns. I generally welcome immediate purchases. I will not create holds or exclusive listings, following Mercari's basic rules. Even if negotiations are in progress, I will prioritize those who make an immediate purchase. Thank you for your understanding. For a smooth transaction, please send a message after purchase. I will ship anonymously using Yu-Pack Mercari, etc. Thank you for your understanding. Below are the product details. Product Name: Aqua Esthe Sonic (original model) Functions: Sonic vibration massage, PEEL mode and EMS mode available Color: White Size: Approximately 170mm with the cover attached, as shown in the photo Accessories: Charging stand, AC adapter, instruction manual
