This tool sets the amatures apart from the pros! Perfect separation sets perfect results. For best results adhere natural eyelashes to the silicone shield or rod. Apply a thin layer of adhesive to the natural eyelashes before using the y tool if needed. Do not try to force the eyelashes to comb if they are dry/hardened. Comb through wet natural eyelashes for perfect separation. After touch up and double check with separating tool. Make sure to not pull the eyelid up so much the waterline is exposed.
