I searched high and low for a stylus wand and well I came up empty. But just as hope was tossing itself out the window I found some keychain wands on amazon that were made of metal. So I did a little bit more searching and I found some replacement stylus tips.
You can find the wands easily on amazon. As for the tips I used these ones. I cut the ends off to expose the rubber, drilled a hole into the end of the wand and glued them in. Easy!
...but I bet you could just slip these on the end of the wands and make your life that much easier.
