What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Cushions against knocks and keeps metal off metal. It will not stop a hard impact or weight on top of it.
Detail 02
Stays shut when the bag tips over. Watch the rim against the zipper teeth when inserting.
Detail 03
Cut for the smaller shank sizes. A tuba or tenor sax piece will not seat properly.
Detail 04
One piece per pouch. If you swap between two mouthpieces regularly, plan on buying two.
Detail 05
Hides wear from being pushed in and out of case pockets, but is easy to overlook on a dark stage floor.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is cut for trombone and alto saxophone mouthpieces. For tuba or tenor saxophone, the larger N275 is the correct one.
Large-shank trombone pieces are noticeably bigger than small-shank. Measure yours against the pouch dimensions before ordering.
Neoprene absorbs bumps and prevents scratching. A serious drop onto a hard floor can still dent a rim through the padding.
It is a plain zippered sleeve meant to go inside a pocket or bag rather than hang from the outside.
