Bikemonger says..... A pointless piece of frippery or a welcome touch of whimsy and reflectiveness. Your decision.

PDW says..... Add a little flair and extra visibility to your ride. A Saddle Charm adds character to the tail of your whip! Made of our woven handlebar tape, a sturdy thread locking loop, and highly reflective 3M™ trim, our Saddle Charms can be attached to the rails of your saddle, the bag loops on a Brooks England saddle, or just about anywhere on your bike or bag for a pop of added safety and fun.  They may even give you a bit of extra luck.

They also make neat key fobs so with that double-whammy in mind, they make great presents.
