3M E-A-R™ Classic™ earplugs 310-1001, without a cord. When you roll them thinly with your fingers and insert them into your ear, the material returns to its original shape, thereby blocking sound. One set (1 pair) per paper case. They will be shipped in a bag as shown in the image, inside a Yu-Packet Plus box. Although they are unused, I have checked the contents to confirm the quantity before listing, so please refrain from purchasing if you are concerned. Earplugs E-A-R™ Classic™ #3M #earplugs #earplugs
