【Soothe Ear Discomfort】 Gently care for the "stuffy ear" or "unpleasant pressure" caused by changes in air pressure or your physical condition with the power of air (negative and positive pressure). This is a self-care tool that allows you to easily adjust ear pressure at home. 【Versatile Care】 In addition to supporting ear clearing due to air pressure changes during flights or mountain climbing, or after diving, it can also be used to alleviate heavy-headedness caused by air pressure and tension from long hours of desk work. 【Soft Silicone Gentle on Skin】 The nozzle part that directly touches the ear is made of soft, high-quality silicone, similar to earplugs. The 3-stage design fits snugly into the ear canal, efficiently transmitting pressure while preventing air leakage. 【No Power Required, Simple Operation】 A simple design where you just grip the palm-sized pump. No batteries or charging are required, so you can use it anytime, anywhere, whether you're out and about, on a plane during travel, or at the office, whenever you feel the need. 【Compact and Hygienic】 Lightweight design with a total length of approximately 11cm. The nozzle part can be removed and washed with water, allowing you to keep it clean at all times. Its size won't be a burden even when placed in your everyday pouch.
