100% Japenese stainless steel Perfectly pointed to achieve precision tweezing movement Hand-filed and aligned to grab the hair with accuracy Non porous surface for easy cleaning & disinfection Tweezer Care Tips Keep clean by disinfecting and cleaning the tips with alcohol. For improved tweezing adjust the spring tension, in instalments, by gently pulling apart the two halves of the tweezer until correct tension is achieved. Once the tension is increased it cannot be decreased again. Avoid dropping the tweezer as it will dull the tip and throw the tweezer out of alignment. Keep the tweezer at secure place out of reach of children.
