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. The Rubis 1K920 Needle Nose tweezers are designed to remove ingrown beard and moustache whiskers. They can also be used to tweeze ingrown hairs that are still under the skin and blackheads, too. The tips are extremely sharp and resemble a needle. We do not recommend sanitizing coated tweezers with a chemical but using mild soap and water. 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.
