The three dinosaur toys move with a wind-up mechanism, but their movement isn't very good. I've marked them as "as is." The Tyrannosaurus Rex (no wind-up mechanism) looks like it's from Jurassic Park, but I can't say for sure. The size of the dinosaur, the Iguanodon, is about 21cm long. The items are clean, so please enjoy them as a display piece. Due to the "as is" condition, please refrain from purchasing if you are looking for perfection or are overly concerned about details. ☆ Promise: We will ship within 24 hours of confirming payment.
