Makeup Geek Full Spectrum Eyeliner ($9.00 for 0.04 oz.) is supposed to be an “ultra creamy” and “ultra pigmented.” They have a smoother, more waxy consistency, so they skim across the skin without tugging or dragging, but the pigmentation varies a lot from shade to shade, though it fell between semi-sheer to semi-opaque in one stroke. They weren’t particularly buildable, as they seemed to push the color around rather than really gradually build it up. They are really, really soft, so use less pressure than you think or else chunks of the eyeliner will break off. They wore between six and seven hours on me before migrating. Their biggest upside is comfort; very creamy and soft, but the downside is weaker pigmentation and wear. As an aside, the price point seems a little high for the brand, given that eyeliners and eyeshadows are (usually) similarly priced, but these are 50% more expensive than the eyeshadows.

Makeup Geek Cobalt Full Spectrum Eyeliner ($9.00 for 0.04 oz.) is a bright, medium-dark periwinkle blue with cool undertones and a matte finish. It had semi-sheer coverage in one pass, which was buildable to semi-opaque (somewhat uneven) coverage after going back and forth multiple times. There was a very faded quality about it once applied to the skin. It lasted for six hours on me. Lethal Cosmetics Harmony (P, $15.50) is darker (90% similar).

It had semi-opaque pigmentation in one stroke, which was hard to layer/build as it would thicken over some areas and pull color away in others, leaving behind an uneven result.
