Don't buy it
This company had a prior nail hardener - "Iron Nails" - THAT WAS the bomb dot com.  They replaced it with this product a few month ago.  DON'T WASTE YOUR MONEY.  YOUR NAILS WILL STILL BREAK - CHIP - PEEL.  I have tried to find the "Iron Nails" but you cannot get it anymore.  My manicurist cannot get it either. AGAIN - DON'T BUY THIS PRODUCT.  If I could give it no stars I would.  WASTE OF MONEY!!
