Borosilicate Glass Septum Retainers

When compared to regular glass, borosilicate is safe for initial piercing, resistant to chemicals, scratch- resistant, less susceptible to fractures, resistant to thermal shock, and not poured into molds. All our glass jewelry is handcrafted in St. Louis, Missouri.

MM Glassworks strictly uses borosilicate glass that is hand made in the USA. Borosilicate Glass is scratch resistant but still fragile and should be treated as such. All glass is guaranteed to arrive scratch and breakage free. We will package each order in a foam insulated box free of charge. Borosilicate glass is autoclavable. Do not use harsh chemicals on any jewelry. Do not wear in the shower or while swimming. Wash with antibacterial soap, but take caution while removing; glass will break if dropped on tile or cement.
