I picked this up from The Warehouse on sale a while ago as I was looking for a nail hardener to use, and had heard good things about this one.
It comes in a clear bottle, with a normal brush. This doesn't smell too strongly, which is good. It's an average consistency, not too thick or thin however one time I went on holiday for a couple of weeks and when I came back mine had gone all goopy and thick, not too sure why that happened as I screwed the cap on tight but oh well. This did help my nails, but you have to use it continually or it stops working as well which is quite annoying.
I would probably buy this again, it's a good product for strengthening nails but when you stop using it the effects reverse a bit.
I brought this to help strengthen my nails and I do not think that it really helped my strengthen my nails that much however I did not notice it making them weaker either as others have mentioned. I do think that it is a nice base coat and is a really nice easy product to use with a brush size that is a good size
