Thank you for viewing. *Please be sure to check the product description and profile. Shipping takes 4-7 days, but if the timing is right, it may be possible to ship on the same day to 3 days after payment is completed. I will do my best to respond as quickly as possible. These are special joint parts made by molding from genuine parts, designed to securely fix official Mini 4WD 2-lane courses (e.g., Tamiya brand). There may be slight chips or distortions during production, but this does not affect usability, so please understand. Recommended for those who are having trouble with broken or lost joints! Simply snap them on for easy installation, preventing slippage and unevenness during races. Image 2 shows a comparison with the genuine part. The product color is clear. Thank you.
