This works same as a plucked however instead of plucking 2-3 hair at a time it plucks more hair. Just bend spring with gentle pressure between fingers. Place it close to skin and move it in opposite direction of hair growth and that's it. Hair gets stuck between closely packed groves and when spring becomes straight they come out with roots with movement. It's not a pain free tool. It hurts, pain is as same threading will cause may be little lesser however it will not cause cuts which can accidentally cause sometime in case of threading. Its work faster than a normal plucked and you can pluck hair from upper lips, eye brows, forehead, side-locks and chin.
