They stand about 3" tall or 4" long - not big enough to use in an attempt on the Iron Throne of Westeros, but suitable for a number of gaming purposes. They are the same size as the small Bandai figures I use for giant monster gaming, and even have the same 'man in a suit' feel in some cases. They will work for skirmish games like Songs of Blades and Heroes with no problems, and they will all fit on a 60mm frontage for HOTT, if you feel that way inclined.
Like any cheap toys of this nature, paint has been blobbed onto them in an arbitrary fashion, but they should take a drybrush, and some painting of the teeth and claws OK I reckon. I will probably give one a go over the weekend and see.
These two are my favourites. I can certainly see the winged serpent in a monster game, and I love the hooked forelimbs of the brown one and the large, fish-like, fin on the tail.
Oh, and this was just one bag. When looking through the racks I realised that there were three different bags on offer, each with six dragons; a total of eighteen individual designs. I didn't notice anything too out of the ordinary in them, aside from one bag which featured a two-headed dragon. If I have a spare five dollars in the near future I may pop in and get that one.
