AK paint pens

Newish on my workbench, are some AK paint pens. I'm a big fan of the MiG oilbrusher, it's a really handy device to have around for quick touch-ups, and these pens might be even better.First impressions are good. The paint flows well, and seems pretty opaque. Basically, painting with no cleanup at the end. The pointy tip isn't going to work for really fine work, but for a lot of jobs, it's OK. One job I have found them perfect for, is painting moulded on handrails. My only moan is that the colours are quite light. RCM007, brown, looks to be quite a dark shade, close to my favoured track colour, and the shade most useful for the oilbrusher. The results are a poor match for the pen casing, quite a bit lighter as the work on the Ratio pallets shows. I like the pen format, but I think I need more experimentation to find the colours I need. They will be out there, I just need to locate them.
