Well, sad to say that I'll be returning Bronze today. I used my best primer AND a bronze cream base eyeshadow (by Dolce & Gabbana, they are AMAZING when it comes to longevity/staying power-- I even use 'Nude' as a brightening eyeshadow base to make colors pop and it LASTS. ALL. DAY.) and the Bronze eyeliner pencil still began to crease minutes after application. It continues to break my heart because it really is a gorgeous shade of Bronze... I have A LOT of bronze shadows/cream shadows, etc. but something about the tone and depth of this shade enhances my brown eyes like no other. I've created a signature bronze smokey eye incorporating it, but now I'll have to return it in hopes of finding a decent replacement.
It seems to stay decently on my lower lash line, so maybe it's best used as an eyeliner and not a shadow...
