Hi Janine....I too used this nail pen for my nails.  I still have several (8) left.  You can still purchase them on Ebay and if not, I would sell you mine.  I no longer use them. I found another treatment that is completely AWESOME, Talika Nail Regenerator Serum.  It comes in pen form and you only need to use it for 28 days to see guaranteed results.
