Large rectangle topaz stones are set in sterling silver prong settings where 4 pearls on sterling silver Figaro chains dangle on each. The base of the "sound cancelers" fit reusable foam earplugs, like Hearos. Just roll the flat end of the earplug and slip it into the hole at the base of the sound canceler. Once it's time to get new earplugs, just pull it out and insert a new one!
As always, you will have free cleaning and polishing with KING RELD for the life of your product.
Earplugs are removable and interchangeable. One size fits most.
