⭐️ 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. We can include them for an additional 500 yen. Please comment if you would like them. ⭐️ Washers are not required. ⭐️ If you have any questions about installation after purchase, please feel free to contact us via the transaction message. Color is silver. Other colors are also available. Please see our listings. 【Silent Wheels (approx. 80mm) x 2, Special Spacers x 4】 We have created special spacers (made of metal), eliminating the need for the troublesome washer insertion process. Thanks to these spacers, even those who are not good at delicate work can easily replace their 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 has almost no noise. 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.
