Adjustable Mouthpiece

145mm of flexible, bend-it-to-where-you-want-it mouthpiece. Can be trimmed to length with wire cutters, as there IS a wire embedded into the wall of the tubing.
Medical grade plastic. Softer than Nylon.

If you control the air flow with the tip of your tongue, you will likely want to nip the tip off of these, as the slits stop your tongue from blocking back-flow through the blowhose.
