Scale Model 3D Wooden Puzzle series consists of locomotive trains, cars and trucks all built from laser cut wood pieces that are connected by the slots without using any glue. It is an ultra-precise 1:80 scale model. Recommended for ages 14 and up to build alone, but it would even also be a good bonding project to work on it together with eager and curious younger adults with assistance – making it a great STEM learning with fun!
