FX Lashes in a J Curl provide a natural, gentle sweep and are the easiest lashes to apply. Their shape makes them compatible with most natural lash shapes. The long body of the lash gives a large area of adhesion on the natural lash. Lash FX synthetic eyelashes are waterproof, heatproof and chlorine proof. They are extremely light and comfortable and can last up to 12 weeks when cared for correctly. These lashes come in a small pot, and are available in lengths from 6mm to 15mm, and in thicknesses Fine (0.10), Thick (0.15), Extra Thick (0.20) and Super Thick (0.25).
