3D Gravity Knife (Dummy Knife) x2 Size: Approximately 7cm (11cm with blade extended) x 4.4cm x 2.3cm This is a plastic, somewhat fidget spinner-like toy for killing time. (When you shake it while holding the light green part, the purple part opens, the orange blade appears, and when you shake it the other way, the purple part closes and the blade remains out. You can also put the blade away by shaking it slowly again and repeating the process, so you can enjoy taking the blade in and out with one hand.) There are small scratches. 3D Gravity Knife Hand Spinner Stress Relief Standing Rotating Blade Safe and Secure Interesting Goods Folding Retractable Carrot Toy Fake Toy Fidget
