Let me start by saying this copper mica powder is a game-changer for resin art! The rich, reddish-brown metallic shade is absolutely mesmerizing. I used it in a clear epoxy project, and the results were jaw-dropping - like molten copper frozen in time.

The versatility surprised me most. As one reviewer mentioned, you can achieve completely different looks based on your finishing technique. When I sanded heavily, I got this beautiful uniform metallic finish. But leaving it slightly textured before clear-coating? Boom - instant lava-like molten metal effect that gets compliments every time.

What really impressed me was the coverage. Just a tiny pinch goes an incredibly long way - my 50g container will last through dozens of projects. Unlike some pigments that weaken the resin, this maintained perfect hardness and didn't affect cure time at all.

The cosmetic-grade quality means it's safe for various applications beyond resin too. I've experimented with mixing small amounts into clear nail polish (hello custom metallic manicures!) and even used it to tint homemade candles with gorgeous results.

Packaging deserves praise too - no messy spills during shipping, and the powder stays perfectly contained during use. After trying multiple brands, MEYSPRING's copper stands out for its intense color payoff and consistent quality across batches.

Pro tip: Combine it with their bronze pigment like another reviewer suggested - the layered metallic effects on my epoxy countertop samples look professionally done. Whether you're into resin jewelry, river tables, or decorative pieces, this pigment delivers stunning results every time.
