I almost posted warnings about Rosewood recorders ...and mouthpieces in particular. I am one of those people who are seriously allergic to Rosewood...and Cocobolo is the worst of the lot. It took me weeks to recover from the one turned Cocobolo lidded container I made. (Rash on hands & wrists,,,and a few other places)

I knew of one person whose lips blistered from playing a Rosewood instrument.
