This is a set including self-made aluminum wings that can be attached to the Daiwa Crystia Variable Adapter, and special washers to prevent loosening. The washers are stainless steel special washers also used in the Crystia Air Variable Adapter. They are effective in preventing the wings from rotating and preventing screws from loosening. The weight of the wings is less than 1g each. This is a handmade product, so there may be some minor scratches. Please refrain from purchasing if you are concerned about this (please judge from the photos). ※【The variable adapter in the image is not included】 Please feel free to ask any questions. Thank you.
