I love OPI. My first purchase was nail envy,:11: but I opted for the matt version. It's done wonders for my nails. They went downhill after I had acrylic tips, but are now natural, long and very strong. Mind you, I now buy it off someone who was selling it on eBay and now only pay £4.99 a bottle.
I had a mini bottle of the pink nail envy and didn't really like it as it thickened quickly and also didn't go on very well. I'm just hoping that the TSV has colours in it, as I've yet to try those, although if it also includes the avoplex oil I may well opt for it anyway - although I'm currently well stocked on that.
