Reflective Biker Skull Stickers
Do you cycle everyday? Or are you just someone that hangs around dark roads a lot? Then these reflective bike stickers are just the ticket. Obviously it's safety first and fashion second but why leave the house looking like a lollipop man when you can step out with these babies? With a skull-come-bike design that's just a little bit amazing they're easily noticeable and come in packs of three; two small sizes for your bike or arms and one large sticker, perfect for your back or face if you're out trick or treating maybe? But in all seriousness, they are fully reflective and can be stuck just about anywhere, protecting you from passing traffic and a style disaster all at once. Pack contains 1 large and 2 small stickers.
