Finally a proprietary cap for new Theo Wanne mouthpieces, designed and manufactured by Theo, to protect the mouthpiece with reed on.

Theo Wanne™ mouthpieces come standard with a reed replacer cap which protects the mouthpiece in storage, and when traveling, better than any other cap in the world.

However, it cannot be used when the reed is still on the mouthpiece. Use the Reed Keeper™ cap when you wish to leave the reed on the mouthpiece, such as when you are on stage, or during practice sessions. The Reed Keeper™ Cap will STILL protect the mouthpiece tip, even when dropped!”
