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"

Finally a dual vertical stand with a stable build, quality materials, and snug fit for MacBook Pro
Color: Black Walnut, Color: Black Walnut
I don’t normally write reviews but I’ve had so much trouble finding an adequate vertical stand for two MacBook Pros that doesn’t worry me every time I look at it. I can finally say with confidence that I won’t need to replace this one. Not only is this stand attractive, it is simply a lot more sturdy than the all-metal “industrial” stand that it will replace because my MacBooks fit into it without wobbling, it has a wide surface area base, and its overall fairly heavy due to a solid wood + solid metal build. This vertical stand stands apart in the two areas that my previous two stands have failed at: 1. A snug fit with a protective lining so that the laptops don’t wobble and bump into each other (the dual Omoton I have suffers from this terribly where the laptops bump and lean against one another) 2. A solid base with enough weight to prevent the stand from tipping over from an accidental bump (my single-laptop human centric mount is beautiful, but the base is too light and narrow so that any decent contact feels that it might tip over) This stand has a very solid build quality with a nice weight to it which is comforting when potentially storing two expensive pieces of hardware in a vertical orientation that lends to tipping over (MacBook Pros are absurdly well over $2k a piece now on average). This is now the third vertical stand I’ve purchased for my two MacBook pros (work & personal). It’s not my third because I compulsively purchase things I don’t need (though I do do that), but rather because the previous two models felt unstable and carried a greater risk of damaging a few thousand dollars in equipment. Anyway, this is my first purchase from this brand but I highly recommend!

Perfect for laptops, tablets, Remarkables, Kindles - you name it! This dock is perfect!
Color: Black Walnut, Color: Black Walnut
Coming across UPERGO has been a blessing. To find items of this caliber without having to pay a mortgage payment on it is a lifesaver. It truly is, and I have found that based on my desk setups in my office, UPERGO has not let me down with any of their products. I had already previously owned a UPERGO Vertical Laptop stand. I use that one for my productivity desk for my work laptop and my personal gaming laptop. So, I knew its quality was legitimately top notch already. The problem I ran into was a workflow issue. I have four portable devices that I carry every day at some point: Microsoft Surface Pro 13", Remarkable Paper Pro, Remarkable Paper Pro Move, and a Kindle Colorsoft. The problem is that I did not want to keep them inside the desk drawer that I use. So, I need something to help save some space on my desk and sort of dock these items when there were not in use. I set one on each opposite side of my desk and that worked out perfectly. I was able to save desk space but also add a bit of protection for these devices. I could adjust the slots, if needed, but it worked out just fine. And the material inside gripped these devices perfectly. Once again, UPERGO has been able to build a product that fit ideally into my use-case. This time, albeit in a slightly different manner, but it was exactly what I was looking for.

Surprisingly Amazing!
Color: Walnut, Color: Walnut
I bought this expecting it to be a cheaper product I would use until I bought something better. I was very surprised to see how nice it was! Very solid and non slip surface on the bottom. The wood on it looks great and one of the most awesome things about it is you can manually adjust it to fit your laptop. I have a heavy16 inch MacBook Pro with a case on it and it fits perfectly in this stand, after adjusting it, of course. I ended up buying another one for my work office too. I can’t wait to try other products from this company.
