I will strive for courteous service. Comments are not needed. Thank you very much (^^) 【Large Set of 100 Sets (200 Pieces)】This is a high-capacity earplug set that emphasizes cost performance. Each set is individually packaged to prevent oxidation and natural degradation from exposure to air. Disposable and hygienic. Comes with a convenient carrying case. 【Reduces Ear Strain】While allowing you to hear the sounds you want to hear, it reduces the overall volume of sound entering your ears, reducing damage to your ears. It helps to relieve sound stress. 【Fits the Ear】The soft material won't hurt your ears even after long hours of use. It's a soft type that's gentle on the ears and easy to put on. It easily becomes thin when pressed with your fingers. Insert it into your ear, and it's ready to wear when it returns to its original size. Smooth surface finish with minimal irritation. 【High Soundproofing】It can be used not only in large concert halls, live venues, clubs, and outdoor events, but also in everyday environments where you are exposed to loud noises that affect your ears, such as karaoke, pachinko parlors, noisy cafes and restaurants, airplane noise, and construction sounds. It effectively reduces the volume while still allowing you to hear the necessary minimum sounds, so you can hear your phone ringing and conversations without any problems. It can effectively block harmful noise. 【Various Scenes】For travel and business trips, when you want to concentrate on studying or working, when you want to sleep soundly on the Shinkansen or airplane, and when you want to immerse yourself in reading or thinking. For noise control in your neighborhood, for those who are troubled by their partner's snoring, and when you want to concentrate on studying or reading. 【Easy to Wear】 It easily becomes thin when pressed with your fingers. Insert it into your ear, and it's ready to wear when it returns to its original size.
