Our Hand Tile is a complete game-changer. If you are not used to working from your hand it may take some practice - but you will get it. If you find it easier to start from working on the tile without strapping it on your hand you can also do that. We recommend going back and forth to try to ease your way in. One of the many reasons we love hand tiles because you can set up your lash strips and then save the tile for a later date. It also creates less strain on your eyes, neck, and back, by keeping your hand elevated higher. Our tile is numbered from 7-14 mm but feel free to place whatever lengths you want, you are the creator!
