This is the second of the Barry M Aquarium collection that I bought last week - Caspian.
This is three thin coats, with no topcoat.
Caspian is a really pretty gold foil. To be honest, I can't really see any duochrome in there, apart from a slight pinkish tinge to it, especially in the bottle, but it is a really pretty colour, and I found it very flattering with my skin tone.
The formula is good - application is smooth, and this dries really well.
I find that these types of foils sometimes wear very quickly at the tips, but after a day at work with plenty of typing, it's still looking perfect.
These are on sale in Superdrug and on Barry M's website for £3.99
