Pens as a fundraiser?

A friend of mine suggested making logo pens with a catchy phrase on them and selling them as a fundraiser for the Avon Walk. I think that's a great idea, but I'm not sure what phrase to put on them. Maybe "Save 2nd Base" or "Save the Tata's" or something along those lines? But, is it worth doing? As in, will people actually buy them? I'm wondering if I could buy say 10 and see how that goes first instead of having to by like 100. Maybe I'll keep this idea on the back burner for a little until I can decide on a catchy phrase and then need to find somewhere to order them first that will sell in tiny quantities.
