This is a used Fusion Triple Trumpet case. I have stored a flugel and trumpet in the case with no issues. I do not have 3 trumpets to try but would think that 3 full sized Bb's would be tight.

All zippers, straps are intact and in good working order. This is a great bag - just a bit more than I need for storage. There is a little fraying on inside pocket where mouthpieces are stored

I do not have the removable accessory panel noted at the fusion bags site. 

Included is one soft padded sleeve that will fit a Bb Trumpet. There is no additional foam or padded blocks.

Trumpet / Flugel shown are for illustration only and not part of the listing

New these bags look to sell $545 CAD before tax.
