I was trying to demonstrate Ossun Two Step to someone at work, and the bellows came separated from the frame.
It had been making a funny sound for a while, like flatulence escaping from somewhere besides the reeds. I now summise that there was an unglued area on the bellows frame, and it finally gave way.
Luckily, this is my $20 First Act accordion. Now I will be able to take this bellows, and connect it to the bellows of another toy accordion, and not run out of air so easily.
