You get perfect nails!
I've been using these acrylic forms for about 7 years now.  I got my original box from Sally's Beauty Supply, but they're actually a bit more expensive at Sally's plus you have to pay for shipping.  I'm finally ready to order another box because the forms that best fit my nails are worn out and although you get a few of each size in each set, after all these years I've finally worn them out.  I'm happy to pay for these forms as you end up with perfect nails once you have a little experience using them and in the long run you save a small fortune over going to the salon.  I never did get perfect results at the salon, no matter how prestigious or expensive the salon was.  These people are always in too much of a hurry and never left my nails in the shape I requested.  I get compliments on my nails constantly and jaws drop when I tell people I do them myself.  These things do take a bit of trial and error though.  The first few times, you should allow plenty of time, but after that you'll get perfect nails quickly and easily.  No endless buffing!  Remove the form, file  and smooth the edges, and apply polish.  My acrylic nails and polish will last four to five weeks without lifting or peeling.  Four weeks in, I'm still getting compliments.  After that, the regrowth becomes apparent and they start looking a little ratty.  Time, once again, for my own private spa day without having to get in the car and driving somewhere to pay someone to do something I can do myself far better and for pennies each time.
