They're quite large, considerably bigger than my metal Citadel Daleks which I think were late 80s / early 90s, and made of very bright orange plastic. They look like they'll paint up reasonably well. Interestingly, they are more or less to scale with the police box the comic gave away a few months ago. It'll be interesting to see if there's ever Doctor or Companion figures to go with them.
Oh, and incidentally Jo Grant (on the left in the icon) will be returning in this autumn's Sarah Jane Adventures. Probably wearing rather more, which since she's 61 these days may not be an entirely bad thing.
