The Rubis Ion is an antibacterial-coated pair of tweezers which allows both precise and also hygienic use. The special coating releases silver ions that neutralize bacteria, germs and other pathogens. You benefit from considerably more hygiene. Straight tip tweezers are universal in design and good for removing chin hairs and stubs. We do not reommend stanitizing coated tweezers with chemicals but using mild soap and water to clean. We recommend that you always use the protective cap provided when storing your Rubis tweezers after use. Every pair of Rubis tweezers is handmade and although the tips are durable, their functionality may be compromised if the tweezers accidentally falls on a hard surface.
