[Soft Comfortable] Made of an incredibly lightweight, non-clogging soft silicone material that doesn't feel uncomfortable to the touch, the engineered comfort fit ensures a comfortable fit even when worn for an extended duration. [ Highly Effective] Designed in the shape of a 3-flange Christmas tree, very effective in preventing water from entering the ear canal and reducing the risk of ear infection. [Buoyant with detachable cord] These earplugs are easy to use and lightweight. So when you're in a pool and they fall out of the ear canals, they'll float on the water, making it easy for you to catch them and put them back in again. Each pair comes with a strong detachable lanyard that can be hooked into the goggles while swimming. So you don't worry that you will hardly find them in the pool if they fall off. [Multiple Use] Washable and reusable, perfect for swimming, showering, bathing and other water sports. They are also effective in reducing and blocking sound during works, construction and other noisy events such as music festivals, discos, etc. Number of shipments: 2 pair
