Set of 5 brushes for wheel markers ・Hole diameter: 5mm ・Length: Approximately 50mm to 60mm Please note that there may be slight variations in length. If you are concerned about this, please refrain from purchasing. If you have a desired length, I can make them for you, but it will take some time. These brushes are flexible and durable. I also use them, and they should last a long time if used gently. ※ No price reduction ※ Shipping only on weekdays
