The trapezoidal nail buffer is a valuable tool for nail care, ideal for preparing the nail plate and smoothing the final layer of gel or acrylic. With two sides of different hardness, 100 and 180, it offers the ability for precise shaping and preparation of the nails before applying acrylic or gel. The foam material used ensures comfortable and effective use, making it easier to remove remnants of semi-permanent polish and the smoothing process.
