“What material is used in the construction of these replacement discs?”

1-1 of 1 Answer

• The replacement discs are made of aluminum oxide, a naturally occurring element that is extremely hard, second only to diamond. Aluminum oxide crystals are non-airborne, hypoallergenic, and antibacterial, which helps prevent adverse reactions and reduces the spread of bacteria that may cause irritation.
