Features: brand new and high quality Stop at any for time, easy to carry. The main function is to place it between the tire and the ground when parking, effectively preventing the car from slipping back; especially parking on bad roads, which can effectively improve driving safety. With a handle strap on the back, it is more convenient to carry and move. The slope is reasonably designed to fit more closely to the tires, suitable for large and small vehicles, and durable. The concave-convex groove design at the bottom increases the friction with the ground and prevents sliding more stably.
