the BEST for anything from subtle shimmer to hard chrome [SEP] This palette has become one of my favorite nail tools. I've been using it mostly on acrylic dip powder, but have also used it on top of traditional polish with a clear coat on top. if you apply a light/thin layer (or on dip powder base that has NOT been buffed), it adds a subtle shimmer. If you apply it more thickly AND buff it with the eyeshadow-type applicator, you can achieve a solid chrome look that's really fun as well. I enjoy putting it on all my nails, or just on one nail for a fun accent look that still matches my overall color scheme. I've also enjoyed using it on a relatively plain nail for a fine-textured glitter look while other nails have full-texture glitter. It's really a lot of fun and goes a super long way (basically as far as a comparable eyeshadow palette would go). Strongly recommended<br /><br />UPDATE: I've ditched my acrylic powders (long story - I kayak too much) but couldn't let go of this shimmer. Turns out it works on traditional nail polish as well. You can apply it directly on top for a chrome effect, or BUFF (not file) the surface gently then apply for a soft shimmer. In both cases top with clearcoat. I still love this palette!
