⭐️ For those with Classic Flight 2-wheel models, the original screws will be too short and will not allow for installation. You will need two special low-profile screws. These are available for an additional 500 yen from the current price. Please comment if you would like them. ⭐️ Washers are not needed. ⭐️ If you have any questions about installation after purchase, please feel free to contact me via the transaction message. The color is clear black. Other colors are also available. Please see my other listings. [Silent Wheels (approx. 76mm) x 2, Special Spacers x 4] I have created special spacers (made of metal), so you don't need to bother with washers. Thanks to these spacers, even those who are not good at delicate work can easily replace the tires. "With resin spacers, there is a risk of cracking." I also use a 2-wheel Topas for business trips, and it is very light and almost silent. It makes a dramatic difference. Although it is new and unused, there may be some scratches, so please refrain from purchasing if you are concerned about this. If you have any other questions, please ask.
