Manufacturer: Bremner Music Product Name: sshhmute Compatible Instrument: Flugelhorn (Medium Bell) Color: Blue Material: ABS Resin Design: New Zealand Size: Outer Diameter: 140mm Length: 180mm Cork Length: 55mm Cork Outer Diameter: 47mm Cork Thickness: 3.5mm I purchased this new in April through mail order. It doesn't fit my instrument, so I'm selling it. I measured the size myself. There are very few mutes that list their dimensions, so please use these as a reference. Here is the manufacturer's website: https://www.sshhmute.com/products/flugel-horn. Bremner sounds German, but it's a New Zealand company. It seems there are 10 colors available for this product. The design and manufacturing are believed to be in New Zealand. There is one spot on the box, on the lid, where the thin cardboard folded when I opened it. I do not smoke. Thank you.
