Con quay Fidget Valkyrie

The Valkyrie Spinner Fidget is an intricately designed circular fidget toy featuring layered, interwoven petal-like curves radiating outward in a mandala-inspired pattern. At its core sits a smooth ball-bearing ring that allows the outer shell to spin freely, making it as satisfying to use as it is beautiful to display.

You need to spin it to smooth out the bearing, eventually it will spin much better (a few drops of oil will make it even smoother)
Due to the very thin design, do not apply lateral force as this will cause the fidget to bend and the balls will fall out. If that happens, you can insert them and it will work again
