Happy Hen Toys, Ltd. is one of the largest online sellers of PNSO Dinosaurs. PNSO dinosaurs are hand painted and are made of a durable synthetic material. PNSO is dedicated to the research and creation of incredibly accurate dinosaur models. When we evaluate dinosaur genus, PNSO models often win our “best model” award. If PNSO does not win outright, they are usually in the top-rated figures. PNSO offers one of the most complete line of dinosaurs. Happy Hen Toys carries all current PNSO models and adds the new models as soon as they are available.
