Using these Thomas & Friends Mini Train Engines is easy! Just give the engine a gentle push, and it will race along any flat surface. You can connect multiple engines together using the plastic connectors to create your own train. These toys are great for playing at home or taking on the go. Remember, they're only for kids aged 3 and up because there are small parts that can be a choking hazard. When it comes to maintenance, simply keep them clean and store them in a dry place. If you want a specific character, add a note to your order, but we can't guarantee we'll have it. Each toy is sold separately, so you can collect as many as you like!
