How do I use a four step nail buffer, and why do I do it?

Question

The buffer has four sides and they are all different colors and they have steps on each of the sides (SIDE 1: EVEN OUT, SIDE 2: SMOOTH NAIL, SIDE 3:BUFF NAIL, SIDE 4: SHINE NAIL).

Answer 1

Number 1 is usually used on the length of your nails, to shorten and shape your nails.

number 2 is then used on the surface of the nail to remove ridges, be careful with this one, should only be used once a month or you risk thinning your own nail too much

Number 3 is then used to buff your nail, similar to step 2 but not as damaging, this still shouldn't be used too regularly as it is still removing some of your nail.

Number 4, Rub vigorously and you'll have a shine like you've used varnish on your nails. This can be used daily to keep the mirror shine.

The reason you do it.....well that depends on you, its just cosmetic, there are no benefits really.
