My son loves these Dinosaurs and make a good use of the screwdriver and mix and match. Very good use of imagination and hand and eye coordination. Very good toy for any buddying little engineers or Dino lovers. Study plastics, not too many loose parts as such and once made he make them fight too. Good little project that he keeps doing it. For the price paid with discount it’s a great product way cheaper than other high street stores and was delivered super quick.
