Important Notes: In the autumn and winter seasons, skin tends to become dry. When using this product, please moisturize your skin sufficiently to ensure complete contact. This is to prevent a lack of response or a stinging sensation (it is also possible to wipe the electrodes and contact areas during use). 【Inflatable Neck Pillow】Features 6 modes (soft, kneading, acupressure, tapping, automatic) and 15 levels of intensity adjustment. You can adjust the comfort according to your personal preference. (Note: To achieve the best results, please ensure that the electrodes are in complete contact with the skin.) 【Ergonomic Design】Adopts an ergonomic design with slightly raised ends, providing support not only for the back but also for the sides. Ideal as a sleep support item for comfortable sleep on airplanes, in cars, overnight buses, and trains. 【Comfortable and Soft】Uses ultra-mousse material and cloud-like fine velour fabric, achieving incredible softness and comfort. Unlike heavy memory foam pillows, it is very lightweight and reduces the burden on the shoulders. The ultimate comfort solution for air travel. 【Fast Inflation and Charging Design】Can be inflated in seconds. The safety valve properly retains air, maintaining comfort. With a built-in flip, you can quickly deflate or precisely adjust the firmness even while traveling. Built-in USB-C rechargeable battery – can be charged in 1.5 hours and used for up to 20 hours anytime, anywhere. (Note: It is recommended to use it for no more than 30 minutes per session.) 【Compact Bag & Lightweight】Comes with a compact bag – you can fold, roll up, and store the pillow in seconds.
