The badges will make your bicycles more eye-catching.     
 
The badge’s body is made of aluminum.  
On the front of the badge there is a protective film. 
On the back of the badge there is a double-sided adhesive. 
You can adjust the radian by your own.
 
How to use: 
Clean the tube of your bicycle where you want to glue the badge and adjust the radian of the badge until they fit perfectly , then remove the double-sided adhesive sticker and put the badge on the tube and press it for seconds.
When you have adjusted the badges and make sure they have fitted onto the bicycle tube, it wont fall off unless someone tears it off.
