The KOH Natural, Glossy Nail Buffer Set includes great buffers for natural looking nails. There are three buffers; Equalize, Clean and Beautify. Use the buffers in order from one to three. Be gentle, because you are removing the surface of your nails and you don't want to damage them. I prefer the KOH Natural, Glossy Nail Buffer Set, because the files are soft and less abrasive than most buffers. I also use the equalize buffer to file my nails. It is gentle and allows you to shape your nails slowly.
After I have buffed my nails and removed my cuticles I use the KOH Gentle Cuticle Stick. The slanted rubber tip is soft and allows you to gently push your cuticles back without damaging them. 
KOH nail products are designed with gentle nail care in mind. For those of you who do your own manicures and pedicures, I highly recommend checking out this product line. Visit www.kohcosmetics.com/nl/. You will find nail products you didn't know existed!
