You are viewing a new mouthpiece cap/cover for the Roland Aerophone AE-30, AE-20, AE-05 & AE-01 (not AE-10). These are not the original Roland caps, but are my improved design, which does not fall off when knocked: a slight squeeze at the base of the cap is required to fit and remove it. The cap is made from PETG plastic. Any questions please feel free to ask.
