Ton Kooiman’s Maestro thumb rest saved my career as a clarinetist. I had severe pain in my right thumb during the first year of my undergraduate studies and this was the only solution that made a difference. I have been using it ever since – for almost fifteen years now. Ton Kooiman is a brilliant engineer and we are all so lucky he has devoted his career to helping musicians in this way.
