Thank you for viewing! This is Firefly, a handmade workshop in Gunma Prefecture. We are offering the "Twist Katana (Twisted Blade)," a unique sword that extends when swung! The blade is designed in a spiral shape, giving it a cool look that's different from ordinary toy swords. 【Product Details】 Condition: New, Unused Mechanism: When you swing it with a snap of the wrist, the stored blade extends with a "shing!" sound (it extends and retracts using gravity and centrifugal force). Uses: Cosplay props, children's toys, interior decoration, and for shooting videos on social media, etc. Material: PLA (plant-based plastic) Manufacturing Method: 3D printed 【Colors】 Orange Green 【Please Note】 Although it is made of plastic and has no blade, please be careful not to hit people or objects with it. Feel free to comment if you have any questions.
