Sapphire #6 is a light, silvery base with multi-colored micro-glitter strewn throughout. This was a hard color to describe as it ended up being sheer with a grittier consistency that was a real challenge to work with. I tried using it with a fingertip as well as a dampened brush, and I had the best results using a flat, synthetic brush and pressing two to three layers to an area. I'd recommend using a glitter adhesive, though, and it should come out quite complex--almost makes it worth all the effort and fallout. On me, it stayed on well for eight hours but had some fallout over time.
