Stila Sparkle eyeshadow.

uh, so many goldy eyeshadows are awaiting you this week. in my hunt for all the beautiful gold eyeshadows out there i have accumulated quite a few so that i could do one each day ;)
today is Stila Sparkle Eyeshadow.
i bought it in the refill pan form from allcosmeticswholesale.com where it only costs 7.99$.
the pan is quite wide so it could be kept in freestyle palettes other than the specific Stila ones. it contains 2.6g of product. the pan is not magnetised, i attached a magnet on the back for it to hold.
Sparkle is a shimmery and sparkly medium bronze gold with the slightest hint of taupe which makes this a very wearable amongst my warm gold shadows.
it has a very fine texture and is softly pressed so one swipe with a brush will pick up a good amount of product. still it's not fall out heavy. it has a medium pigmentation and applies rather sheer with a soft sheen. it's easily blendable. this is a good colour for an everyday wash on your lid because the shimmer doesn't translate as intense once applied but also can be combined with bolder looks.
somehow it seems to fade after about 4 hours on me, even when i use a primer. it doesn't really crease but the colour and shimmer fade around my crease area. i want to try if this also happens with a coloured base underneath and will get back to you then.
i really like the colour, but it doesn't look as good applied and even worse after some time :(
of what kind are your experiences with Stila shadows?

this is how it looks on me, with MAC Magnetic Fields in the crease. relatively freshly applied.

on another day, also with MAC Magnetic Fields in the crease area, but picture taken about 4 hours after application. the colour is faded in the crease area.
