stila's Turquoise Smudge Stick was unique to my collection and such a pretty color. It was limited edition back in 2013 when I purchased it, but looks like it's part of the regular collection now.
Toffee/Sandalwood duo from Lauren Brooke Cosmetiques. Girl Crush had changed consistency, whereas Glow from the Kathleen Lights quad always looked chalky on me. One half of Toffee/Sandalwood had change consistency as well and was unusable. It was over 4 years old and is a natural/organic ingredient brand, so it had definitely passed it's shelf life.
Lash Domination mascaras from the Countdown to Gorgeous advent calendar. I just really do not like those!
