From their website:
These miniatures have been deliberately sculpted in an 1980’s golden age RPG retro style. Our miniatures are made from top quality pewter not cheap lead. They come unpainted with a plastic base and are suitable for various systems such as D&D, Runequest, Stormbringer etc.
At this moment in time were are developing the range and later this season we hope to have the dwarfs available closely followed by humans, elves, orcs and undead which will be £1 each.
