The Ilu Double-Sided Bridge Buffer is ideal for preparing the nail plate, smoothing the final layer of gel or acrylic, and removing residue from semi-permanent polish. With two sides, it offers different grit - 100 on one side and 180 on the other, allowing you to shape the natural nail as desired, as well as prepare the surface for the application of acrylic and gel. Its foam material ensures a gentle application and contributes to the overall nail care process.
