We finally got these in.
After looking for years, we finally found a supplier in the US of these old fashioned French soap "dispensers"
which were originally designed for French public schools. We find these a perfect solution for busy hand washing centers like the kitchen sink, children's bathroom and outdoor showers...
A simple chrome bracket mounts on the wall and the lightly scented vegetable soap slides onto the rod and is held with a sturdy cap screw. The soap lasts for a long, long time, and we'll soon be offering refills just in case you go nuts and use yours up quickly. Go to AT Shop.
