【Product Description】 Thank you for viewing. This is the Black Nickel model of "The One Device," a device that's been gaining attention overseas. 【Product Features and Expected Experience】 According to the official website, The One is the world's first wearable device that combines three therapies: "light, sound, and vibration." Designed based on over 13,000 peer-reviewed scientific studies in the National Library of Medicine, it is expected to provide the following effects when worn 24/7: ① Sound & Vibration Therapy Many studies have shown that specific frequencies and vibrations have a positive impact on physical and mental health. • Stress and tension relief • Relaxation promotion • Support for sleep quality • Autonomic nervous system balance ② Light Therapy Studies have shown that specific wavelengths of light have a positive effect on brain function and mood regulation. • Mood stabilization and mental care support • Support for concentration and cognitive function • Recovery from stress • Harmony with heart rate and breathing ※ This product is not a medical device. The above are general research findings related to the technologies employed, and individual results may vary. 【Reason for Listing】 I purchased this directly from the official website through personal import. I only tried it on and used it for one day after it arrived, but I decided to repurchase a different design, so I'm selling this one. 【Condition】 • It was only tried on indoors for one day, so it is in a very clean, like-new condition with no scratches or stains. • All accessories (box, chain, etc.) are included. • Alcohol-sterilized and cleaned. 【Price】 Selling Price: 33,500 yen Purchasing from the official website involves the product price plus international shipping and customs duties, making the total cost higher than the listed price. It also takes time to arrive. Recommended for those who want to get it quickly from within Japan, at a price lower than the regular price, without the hassle of importing. 【Shipping】 We will take thorough measures against water damage and impact, carefully package it, and ship it promptly. Please feel free to comment if you have any questions. Thank you.
