Large, highly visible blue mirror Round glass for a wide field of view The mirror is made of hard material, so I believe it's real glass. The reflection is also clear. Installation is specifically for the underside of the handlebars, as shown in the photo. Since my handlebars were up-type, the angle just wouldn't work, and I gave up after using it for a short while. Normally, I would have just thrown it away, but the texture and the quality of the glass surface made me think it was a waste to discard it, so I'm putting it up for sale. The condition is almost like new. (There may be some unnoticed scratches since it was used for a short time.) No claims and no returns, please.
