Product Description Weight: 40.0g Diameter: 62.7mm Height: 23.8mm Shaft Length: 55.0mm This popular clear polycarbonate model "Hibari" now features an LED, creating a light-up spinning top. The clear body with glitter has a cap with a circuit-inspired design. When the top spins, the multi-color LED lights up vividly. (The LED color varies depending on the body color.) The light-up circuit is activated by centrifugal force. The batteries are secured by a screw-on lid, allowing for easy replacement with a screwdriver. ■Button batteries 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 varies depending on the body color. Click on the product image to see the light-up color. Due to the centrifugal switch structure, the duration of the light may vary 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 circuit's spring 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, bend it in the opposite direction for fine adjustments.
