They are also breathable. 【Washable, Reusable & Easy to Put On and Take Off】 MZHOU earplugs are washable and reusable, making them economical and hygienic. Moreover, you don't need to roll them up to insert them. When putting them in, hold the handle of the earplug and slowly insert it along your ear canal (as long as your ear feels comfortable). When taking them out, hold the long handle and slowly remove them. 【Filters Noise and Protects Hearing】 These earplugs have a noise reduction rating of 23dB, making them suitable for a wide range of environments.
