This is a set including one base and one car. I tried attaching a Tomica 20 Alphard. Tomica-sized cars can be attached with the stickers. When the car "drives" makes a right or left turn, the centrifugal force causes the car attached to the dashboard to move left and right. You can use your own Tomica cars by using the included adhesive stickers. Although it is new and unused, there may be initial scratches due to it being a foreign product. Please understand. 【Recommended setup method (tips) for drifting】 For Tomica cars with a one-box shape like a minivan, it will drift well if you attach it "between the front wheels" or "closer to the center from between the front wheels". Also, I think it's a good idea to attach the base with an incline, with the front wheel side higher and the rear wheel side lower. I have glued the Alphard, and I do it that way.
