Because I use my hands a lot in work, my nail polish often chips or cracks. I bought this product in hope that it would help keep my nail polish looking fresh and shiny for days on end. And my dreams came true! The Harmony Gelish Top Coat bottle cost me $12.50 and it works amazingly. It goes on to my nails like silk, does not clump and dries within a few seconds. No matter what my hands go through, when I use this product my nails stay looking perfect day after day. I recommend this product to everyone! Besides, the shipment of the products was great. I never knew if online services were that quick in fact! But this service really left a great impression!
