These are not what you would expect from a metallic or even from looking at them in the bottle. These colors are solid but with a shine. I'm glad I got these, they're beautiful deep rich colors.

Not at all shimmery, and the blue is barely even metallic when stamped. Nice, dark, very opaque colors. But if you're looking for something shimmery, try Celestial or look elsewhere. I haven't yet tried them as base colors, but I do like some of the examples others have shared. Bottom line: I wouldn't have ordered these knowing how they really stamp, but I'm not unhappy enough to return them either.

These colours are incredible! I think they work better as a base coat than for stamping, at least in my current (summer) climate, as they do dry pretty fast, but the texture is great and the colours are amazing. I thought my favourite would be Evil Eye, but I'm actually super into Poison right now. Cauldron makes a great base coat for any celestial-themed stamping, such as the stars and starry flecks on the m055 plate!

These are such beautiful colors. I adore them!

These are all very very dark (stands to reason I suppose). The red and green are beautiful and shiny and intense. The blue I find to be rather dull for a metallic—only vaguely shimmery, and a more muted color. None stamped as bright as the product picture, but they will be good as alternatives to black for stamping outlines.
