Yes, all the lipstick bottles are vegan.
Not only does it mention so on their website (http://www.lush.com.au/shop/product/category/path/228/emotional-brilliance
) but I went to a Lush shop today to look at these lipsticks under the impression they weren't all vegan. Surely enough, the lady helping me with the colours guaranteed me %100 they are vegan, the vegan symbol is on every bottle and if I was still unsure, every colour has the ingredients on the bottle, but I trust her.
I hope this helps.
