EarZzz stylish earplugs offer a comfortable fit. - Model Name: EarZzz stylish - Series: EarZzz series - Colors: White, Black These are the "EarZzz stylish" earplugs. They are a popular product, having achieved six top rankings on Rakuten Ichiba. A set of 2-layer and 3-layer flanges allows you to adjust the noise reduction level. They are ergonomically designed to fit the ear canal and are unlikely to fall out. They are washable and come with a dedicated case. Thank you for looking. I used them once, but they didn't fit my ears, so I haven't used them since (I took them out immediately, so I didn't use them for even 30 minutes). I will disinfect them with alcohol before handing them over. Also, the black earplugs are unopened and have never been used.
