How do I return an item?

Northern Brass Mouthpieces Trial and Return Policy. To obtain the best possible chance of a proper fit we recommend that you initially order at least 2 mouthpieces of the same diameter and cup size with our two different rim options because one of the two rim styles will work better for any given person. For example: Order the 3-66**** (semi rounded rim) and the 4-66**** (semi flat rim) to determine which works best for you. Purchase Only with PayPal to participate in the trial/return program.

While on trial PLEASE DO NOT PLACE MOUTHPIECES RIM DOWN on hard surfaces such as the edge of a music stand or any hard surface. Always place the mouthpieces on a cloth or a towel. Also please coat the shanks of the mouthpieces with valve oil prior to inserting them into the trumpet. This helps reduce shanks marks on the mouthpieces while play testing them.

Trial Period is 3 days. Universally we have found that if a mouthpiece does not work for you right away then it most likely never will. Buyer pays return shipping costs. Notify us immediately after 3 days if you want to return a mouthpiece(s) at with your tracking number with mouthpieces shipped in a USPS small flat rate box or a sturdy box fully insured (USPS insurance is around $3.50 per mouthpiece) Carriers other than USPS is OK as long as insurance and tracking is secured. Refunds will not be made until the returned mouthpiece(s) arrives safely. If mouthpieces are lost in shipping the buyer will need to handle the insurance claims details. Mouthpieces must be returned in like new condition. If no purchase is made a 20% restocking fee will be charged. If a mouthpiece is returned with significant damages such as from being dropped on a concrete floor, bent shanks, excessive shank marks from a damaged receiver etc then additional charges will apply to cover for repair and/or restoration costs.

Exchange: During the initial 3 day trial period for example if you feel that a smaller or larger diameter size or a different cup depth or rim type might fit you better contact us at We will then make one attempt to provide an alternate size once the originals have been returned undamaged. Buyer covers shipping costs on exchanges and returns. Mouthpieces sent on exchange also have a 3 day trial period as above.
