Try before you buy?
We do not currently supply mouthpieces to retail stores, they are only available online. We do this partly because we are a very small non-profit manufacturer – all mouthpieces are hand made ( not from generic blanks). We would be unable to keep up with the demand of supplying retail shops with stock.
However we do have a no quibble returns policy (provided the mouthpiece is returned in as new condition). Furthermore if you order two so that you can decided which size works best, you can get a discount which you keep even if one is returned.
