Standard pencil eyeliner, nice packaging, though the cap looks liable, like others, to crack or come off if subjected to a bit of wear and tear.
Cobalt Blue is, well, a cobalt blue. It's pretty straightforward, and opaque in one smooth stroke.
It feels very... liquidy. Wet, and gel-like. It sets in a matter of half a minute, but is not completely transferproof.
Its smooth, soft consistency makes it a bit difficult to create a bold line unless the pencil is very sharp.
This is simply the liner on bare eyelids; no primer. You can see that on my left (your right) lid, the liner has smudged and transferred onto the top of my eyelid- this happened about ten minutes after application. This problem can be avoided by setting your eyelid with a powder shadow beforehand.
Here's the liner paired with a pink shadow.
Doesn't it look great? It lasted about 6 hours on me before it started to look significantly faded.
While this eyeliner isn't all that I wanted or expected, it's a perfectly nice blue pencil eyeliner, and probably one of, if not the best at the drugstore. I look forward to checking out other colours in the Silkissime line.
