Mini 4WD Original Wheel Puller ver.2 + Reinforced Arm Specification Works with 26mm wheels and smaller, as long as there's a 1mm clearance between the chassis and tire. Removes wheels with just a few squeezes. Press the orange button to release the stopper. The plate is made from 1mm stainless steel, laser-cut for precision and to minimize impact on bumper shapes, to accommodate reverse-mounted wheels as requested by users. Includes a reinforcement plate for increased strength. The shaft doesn't rotate, preventing slippage, and is even more secure with hollow shafts. Easy for even junior racers to use, and users have given it high praise for its ease of use. There may be some scratches from the manufacturing process, but this does not affect functionality. Also available for sale elsewhere, so it's first come, first served. If you're buying multiple units, please let me know in the comments. I may be able to reduce the shipping cost.
