200/200 strength, soft, flat, rectangular buffer. It comes into contact with the nail on a large surface, so it can be used to mattify the nail plate in just a few movements. Because it is soft, it perfectly takes up the curve of the nail plate, making it even easier to use. With CrystaLacs, we prepare the nails with this buffer before using No Buffer Scrub or Spray Prep. It's gentle because it's very fine, it doesn't dig deep into the nail. If this buffer is used to prepare the nail plate, the dissolution of CrystaLac becomes much easier.
