Do you have someone in your life who is a musician? Or someone who just loves music? Why not get him (or her) a personalized key chain or pendant in the shape of a guitar pick? It is made of heavy gauge pure aluminum. This means it is mega durable and lightweight.
It is thick so it won't bend. Keep in mind it is only about the size of a quarter so there is a limit to what can be stamped on it. The font is small, 1/16" but it is legible. It would be similar to this one. *Please note that this is not my work...it is for reference only* A key chain or pendant like this one costs $12.
