The MB5 is a lightweight fiberglass case made for screw bell French horns by Marcus Bonna in Brazil.  The fiberglass shell is surrounded by a nylon cover that is easily removed if repair or replacement is ever necessary.  The MB5 case includes backpack straps, a shoulder strap, several movable foam pads, storage pouch, a double mouthpiece pouch and ID tag. 

The case weighs 7.0 lbs and the dimensions are 23x14x8.5".

Two small interior spaces will hold your small accessories.  The lid includes storage room for two mutes.  The exterior has a small accessory pocket at the top of the lid and a sheet music pocket on the back near the strap mounting rings.

This case protects your horn with a plush interior and a snug fit for the horn body.  The body straps down to the floor of the case to prevent movement.  The bell flare slides into a padded sleeve that rests on top of the body and is pinched slightly when the case is closed.  Truly, we have feared damage from having the bell flare located there, but it never happens.  Never have we heard of such a bell injury to a horn traveling in an MB5 or similar case.  The caveat is that these cases are designed for use as hand luggage, and are not to be trusted to checked baggage or airport baggage handlers. 

This case actually comes in 3 sizes:

  • Standard:  fits nearly all double horns of normal size, Conn, Yamaha, Hoyer, Holton.  Now fits the Alexander 103, though the case is larger than it needs to be
  • Compact: This case is about 2" shorter and has a bit less storage inside.  Fits many Kruspe and Alexander style horns, maybe others.  For Alexander, see the MB5 Baby model.
  • XL: The shell is the same as the standard model, but the interior accessory compartment is smaller and the brace near the bottom to support the horn body is moved outward for larger horns.  Note:  New models a movable interior brace so you should be able to fit a variety of horns into the standard case.  Large wrap Geyer style horns like a Hoyer G10, Duerke LDx5, and Atkinson may be better in the XL

Instruments shown in the photos are a Paxman Series 4 and an Alexander 103.

As with all Bonna cases, many colors are available.  Given a bit of waiting, we're glad to offer this case in any single or two-tone color scheme that you'd like.  We receive shipments four times a year, so 30-90 days is a common wait time.

We try to stock several color combinations:

  • black nylon
  • black & blue nylon
  • black & green nylon
  • black & burgundy nylon
  • black & turquoise nylon

Other colors available include red, yellow, orange, light blue, light green, dark green, purple, grey and pink.

A leather outer cover is also available by special order.  See the drop down menu for pricing.  The leather adds less than a pound of weight.  The leather is stylish and may wear a bit longer than nylon, but you will get many years of use out of either.  The full spectrum of colors is available for leather cases.  Carbon shell is available, which saves less than a pound, but significant weight.

Compared to the MB7 case, this MB5 may be slightly more comfortable to carry as a back for some players, especially those of the petite size, due to its symmetry.  The MB7 may be more comfortable carried as a single shoulder strap case.

Weight: 7 lbs, 12 oz

Dimensions: 8x15x24"

Awesome product!!!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
Wow when they describe these magnets as “super string” they are not joking! Magnets are so strong you must be careful when placing them on your metal cabinet, lest it pinch your finger when the magnet grabs the metal! This is an awesome product. The hooks have a hole in their base that fits over a threaded post / bolt coming out of the center of the magnet and the kit comes with two washers, lock washers, and bolts to attach the hooks to the magnets. Takes about one minute per magnet to assemble. Once on the wall they feel like they will hold a lot of weight though I did not try to test the upper limit. No problem at all holding yard tools and the like. The hooks or arms have a nice rubberized coating and extend about 4.5” out from the wall. At $15 each these seemed a little pricy but wow what a great solution for hanging things on metal walls. They work so well I will be buying more of these! I actually have some other similar very strong round magnets made for a similar purpose … but they do not have the “built-in” hooks like these do and it makes a big difference for the usefulness! Considering all of that I think they are a great value. Item reviewed: MUTUACTOR Updated Super Strong Magnetic Hooks,40lbs, 2-pack

These are great to have
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These are so strong and bigger than I thought they would be in a positive way the price is good for the product. You can take them and put them wherever you need to. They can go on a fridge or transfer to anything magnetic, can go anywhere. These are a need in the home.

Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.

Incredibly strong magnets and thick, robust hooks. Excellent combination!
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These magnetic hooks are really strong. Seriously! Each part is made to carry weight and last. The hooks are built out of thick steel stock. They bolt up to large magnets that grab onto steel surfaces and won't let go. The cabinets in my shop are all steel so these worked perfectly on the sides of the lower units. I have a few #12 AWG extension cords that are bulky and heavy. Truthfully, I didn't think these hooks would handle them. They do without any issue. Another application is a 30' long #10/4 AWG SO cable that powers my powder coating oven. It's usually unplugged and wrapped up. It would often end up on the floor where it was constantly in the way. The outside of the oven is all steel but I didn't want to make holes in it for cable hangers. Again, I didn't think that these magnetic hooks could possibly be strong enough to handle the weight of that cable but they do. And once they're attached, it takes a lot of effort to remove them! Amazing performance!! I'm thrilled with these magnetic hooks. They are super strong and, obviously, simple to use. Importantly, they stay in place as they should. I wholeheartedly recommend these hooks to anyone. Great product! Incredibly strong magnets and thick, robust hooks. Excellent combination!
