Ordered 10 different ones, shipped within 2-3 weeks. There was 1 car missing but I was refunded the same day I contacted the seller. Great product and customer service.
TOP NOTCH SELLER! The whole package arrived early. Three of four items were as described. There was an issue with the fourth and this seller fixed it.
Good quality and it was exactly as described. Well packed and fast shipping. This is definitely the cutest item I've bought in a while. Thank you!
