Most of the Tweezers are hand made. Sometimes if you are buying the same type of tweezers, you used before, it might be slightly different. Try to grab a fan in different part of the tweezers foot. All lash artists have different habits, the way they hold tweezers, where they grab fans etc. Because there are known many Volume techniques, not every tweezers designed to work for every technique. We recommend our Dumont tweezers for Rocking or wiggle technique, only, but try to avoid using very end of the tweezers foot. If you use different technique but like using tip of the tweezers, we would recommend our Flawless Volume tweezers, if you like to grab fan further down the foot of the tweezers, Easy Fan tweezers are perfect. Please check on the product page of our website if the tweezers are suitable for the technique you are using. If yes, you might need to adjust the position of your hand on the tweezers, change the pressure applied to the tweezers or also try different pick up spots on the foot. If this still doesn’t work, please contact us.
