I have a complete set of thumb molds in both oval and round that Donkee sold several years back.  Unfortunately, a couple of the sizes I have used quite a bit are getting really worn and I need to replace them.  But, I have not been able to find a place that carries them to purchase the replacements.  Does anyone on ball reviews know where I might find them?

They work great with the Wizard ball plug, by the way.
