This is a shift knob made from Yakusugi cedar. Yakusugi was designated as a special natural monument by the government in 1954, and all logging is prohibited. The Yakusugi available now is from trees that were cut down long ago, and the quantity is limited, so the price has been increasing year by year. Therefore, please understand that the price is set relatively high. The finish is natural wax. Please check the screw size on the lever side before purchasing. The screw size of the mounting part of this shift knob is 12 x 1.25mm. If your screw size is 10x1.25, 10x1.5, 8x1.25, 6x1.0mm, or 12x1.75mm, it can be installed using the following optional diameter conversion adapters. << Diameter Conversion Adapter Sizes (sold separately) >> ① 12x1.25mm (knob side) → 8x1.25mm (lever side) ② 12x1.25mm (knob side) → 10x1.5mm (lever side) ③ 12x1.25mm (knob side) → 10x1.25mm (lever side) ④ 12x1.25mm (knob side) → 6x1.0mm (lever side) ⑤ 12x1.25mm (knob side) → 12x1.75mm (lever side) (←This adapter will be 23mm longer) 《 Delivery Method 》 Free shipping, but it will be sent by regular mail (Teigai). 《 Other Custom-Made Products 》 If you would like a custom-made product with your desired size and materials, please contact "Wood Studio Craft Miya" through the inquiry form on their HP.
