Left to Right: Sin / Juju / Rehab / Delinquent / Clash
I tried them on my forever creasing lids and they hold up pretty good. Usually it takes seconds before my lids crease after applying a product (with no primer), but the UD 24/7 Shadow Liners last a while with no signs of creasing :)
Here's a closer look at each shadow pencil:
I mainly got the set because I wanted Juju, Rehab, Sin and Delinquent; Clash really didn't get my attention and I haven't used it at all.
Delinquent is a gorgeous purple, but my problem with it is the bright purple shimmer...don't like it at all. I like to use Delinquent it on my lower lash-line/waterline and I use a purple eyeshadow on top to hide the shimmers (I use Inglot Eyeshadow Pearl 446).

I'm definitely getting more of the UD 24/7 Shadow Pencils, I already have my eye on Lit.
Have a great day!
