Environment-friendly manufacturing

Where possible, plastic parts are manufactured in-house using biodegradable material (PLA) which is made from renewable resources. This is good for the environment but it also lets us respond quickly to different shapes of brass instruments that we have not seen yet. And it also gives each part a unique look. Please contact us in case the delivered adapters don't fit your instrument and we will find a solution.
