Nice deep colors
I bought CAFFEINE ROSE and CHERRY. Through a promotion I also received ROSEY ROSE! All colors are pretty. The Cherry is the brightest and most opaque. I was surprised that the Caffeine Rose was more sheer, but everything can be built up. I wiped off the swatches a minute later (with a clean tissue) and the stains were definitely present. The scent is like a light Cherry Lifesavers. There is no taste or stickiness.

Shiny!
While it's not the most moisturizing formula of lip tint out there, nor the most pigmented (in fact these are quite sheer, albeit somewhat buildable and leaves a stain), I would definitely buy these tints again. I've never seen such a pretty, glassy glow in a tint with a thin, comfortable formulation. The tint really shines like juice, even the shades with a milky base. The two shades I tried thus far (Ash Nut and Rosy Rose) also wears almost true to swatch even on my pigmented lips (although the stain it leaves behind may vary) which is rare in K-beauty where most tints either shows up too pale or pull orange or red on me. I wouldn't mind reapplying these tints every so often between the shine and color selection.
