Product Description Weight: 40.0g Diameter: 62.7mm Height: 23.8mm Shaft Length: 55.0mm The popular clear polycarbonate model "Hibari" now features an LED, creating a glowing top. The "sparkling" body with glitter in a clear color is paired with a cap featuring a circuit-inspired design. When the top is spun, the multi-color LED lights up vividly. (The LED color differs for each body color.) The light-emitting circuit is activated by centrifugal force. The batteries are secured by a screw-on lid, allowing for easy replacement with a screwdriver. ■Button battery LR41 x 2 (test batteries included) This is a Japan Koma-mawashi Association certified top, developed in collaboration with Spin Gear and advice from Koma players. The LED color differs for each color. Click on the product image to see the light color. Due to the centrifugal switch structure, there may be variations in the duration of the light due to individual differences in the internal metal fittings and springs. Also, the blue LED is slightly less bright than the green or red LEDs. If the light goes out quickly, you can improve the contact by pinching the base of the spring in the circuit with tweezers and bending it slightly. Bringing the spring and metal fittings closer together will make it easier to light up even with a weak spin. If the power is constantly on due to them being too close, try bending them in the opposite direction for fine adjustment.
