This item is attached to the soles of shoes to create sparks. Unused. We are not responsible for any traffic accidents or other issues resulting from the use of this product. Please use it at your own discretion. I haven't used it, so I don't know how many sparks it will produce, but I've included sample images. It seems like it can be used on motorcycles, bicycles, skateboards, etc. Purchased on Amazon. #Motorcycle #Bicycle #Skateboard #Performance #Sparks #Sparks #Trendy
