Brush pens are an absolute delight to colour with as they allow you to fill in tiny spaces as well as huge areas, all by changing the angle and pressure. These MozArt pens are made in China and have a quality real brush nib, each individual strand making it act more like a paintbrush than a pen. It can create lines from 1mm to 4mm and comes in a decent range of 20 colours.
The narrow barrel is very lightweight and you can barely feel them in your hand, so they're ideal for colourists who don't stop a picture until it's done! The colours are all really juicy and don't leave any broken lines or scruffy bits like some brush nibs do. The point tapers off very finely to get right into all those intricate designs, and the colours are all pretty much identical to the indicator on the end of the pen.
The pens come in a handy storage tray that slides out of a popper-closable plastic box, ideal for taking out & about with you and keeping all the pens in place.
Colouring-wise, the pens perform really well. As they are quite wet, they may show through the other side of certain paper stock, so make sure you test them before colouring a whole picture unless it's a single sided book. Surprisingly for waterbased pens they blend quite well together, creating a nice gradient between shades that isn't quite seamless but good enough. I coloured the following picture from Enchanted Forest Artist's Edition, and I'm really happy with how it turned out.
