These lightweight narrow-mouth wash bottles are the perfect vehicle for storing cleaning solutions, water or acetone. Gently squeeze the plastic bottles to allow for a controlled flow of liquid. The long, curved shape of the dispensing tips will help in accessing hard to reach areas. The precise flow makes these bottles a great tool for lash technicians to thoroughly cleanse eyelash extensions during treatments. Cut back tips to increase flow. To clean, just unscrew and wash out.
