Has anyone seen a small measuring wheel?

[LemonBall]

Hi,

I would like to buy a small measuring wheel so that I can measure the distance on the side of some patterns.

Is anyone familiar with this tool, or would anyone know where to buy one?

Thanks,

I would try a map store. They would probably have what you're looking for. It's shaped like a pen and has a small wheel at one end. Don't know if the resolution would be fine enough for your purpose, but I think it's worth looking into it.
