This is a handmade creation (fan-made) created by working on a 3D printed output. It is fixed by sandwiching it with transparent nuts. It will be stable if you clamp it firmly. It is designed on the assumption that it will be attached to a wig. If you feel that the fixing strength is insufficient, please reinforce it as appropriate. Four U-shaped hair pins are included with the hairpin. Adding pins or clips from the side to the inserted pins will increase the robustness. We also recommend sewing the hairpin parts to the wig with thread. [Size] Maximum diameter: Approximately 25cm The photos are of the same type of product. Please be assured that we will send you a product of the same quality. We decline all price negotiations. Please understand this beforehand. We hope you will find it useful for cosplay, etc. Please consider purchasing this item, keeping in mind that it is a handmade product. We also accept orders and requests. We have prepared a consultation page at the bottom of the product listing, so please feel free to consult with us there if you wish.
