Be sure to secure them with double-sided tape or similar before running. These are processed from Tamiya genuine products. You can create thin tires at a low cost, similar to the other item for sale: "Mini 4WD Low Friction Maroon Thin Tire Finished Product Large Diameter Surface 25.6mm". We will ship via Yu-Packet Post.
