Kärntnerland Harmonika Rucksack für 4-reihige Harmonikas

A little unsure because the inside dimensions are not given on the website, I ordered the backpack for my Saltarelle Ioise, a three row diatonic accordion with 33 buttons and 18 basses. The backpack fits wonderfully and is very well made. And I think, even though I haven't tried it yet, it will pass as hand luggage on the plane (take the sheet music out of the side pocket otherwise it will be tight with the 23 cm!). The carrying straps could be a little better worked out. A connection in front of the chest would certainly be beneficial. Nevertheless, 5 stars.
