Make your nail polish last longer

I discovered that using a 4-steps/sides buffer made my nail varnish last longer. Use each of the 4 steps on all your nails untill they are smooth and shiny. It takes no longer than 5 minutes. Then you dust off the "powder" and apply the colour.

I bought my buffer for 10 danish kr. in Tiger. You don't need a fancy one, a cheap version will do the job.
