The foam buffer is ideal for preparing the nail surface to ensure smoothness on the final layer of gel or acrylic. It is also effective for removing residues of gel polish. Its design includes two sides with different grit hardness, providing the flexibility you need depending on the application. The higher the grit number, the finer the texture, while the lower the grit number makes it coarser and rougher, allowing you to choose the appropriate surface depending on the task you are performing.
