I bought myself a nine pack of Stila Lipglazes for Christmas in 2013. The one con that I had with the product was that they are all so pretty I wasn't sure which to use first!
These are great they over light to medium pigmentation and are very very glossy (or glazzy), they offer different options from nudes to shimmers to brights and glitters and each one is prettier and sweeter then the next. The pen type applicator does take a bit of time to get used to, especially the twisting to get the right amount of product and how to 'swoosh' the glaze around to ensure even coverage.
All in all they are great products, I'm not sure if I would buy the single sets again as the price is quite high but the nine pack that I bought was very reasonable for 9 x 8gm glazes, I think the 'normal' single pack is a 12gm pencil.
