We have only the Compact size in stock: 4.6.26 only one left.

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"

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.

Very Pleased with Room Divider
Size: 4 Panel, Color: Brown
This room divider is even better than I expected. It's sturdy but is lightweight enough that I could get the box up a flight of stairs with no problem whatsoever. It folds and unfolds easily and is very easy to move. And there's no assembly required! It really is woven and is quite attractive. The main reason I chose this item was price (although I did like the way it looked) and I got more for my money than I thought I would.

Works well
Size: 4 Panel, Color: Coal Black
i bought this for 3 reasons. 1. Privacy when changing so I don't have to lock dog out of room. 2. In case MIL comes over and wants to snoop. She won't be able to see my bedroom. 3. A nice backdrop to use when taking photos of the clothing I make. This is perfect for me. My only "complaint" is that it is not the most sturdy thing. I have to finagle it in a way that keeps it from falling over. But for the price, it can't be beat!

Cheap and unstable
Size: 4 Panel, Color: Black, Size: 4 Panel, Color: Black
Although this has nothing to do with the product, it arrived a day later than previously stated. Making me have to create a makeshift room divider the day it was actually needed. When the product arrived it arrived in a box that showed no evidence of damage. Once opened, divider was found inside a plastic cover. Great protector for dust or scratching. The divider was fully assembled so there was nothing for me to do but remove it from packaging and use it where needed. After further inspection the divider was not only cheap and flimsy looking it was absolutely unstable. It would wobble and appears to have been assembled in a rush making some panels crooked. I noted significant damage to the bottom portion of some of the panels both front and back. It does not feel like an item worth the price. The color is as advertised and the product had no smell. The sizing was accurate.
