Thanks. Yes. They are little 10mm wheels. There's an inside core surrounded by 6 tiny ballbearings and an outside wheel with a v groove around the middle.
I got them from eBay a long time ago for fixing rollers at the bottom of sliding mirror doors but I had ordered too small (I needed 40mm ones). They are very useful.
