Oscar Adler & Co. Clarinet Barrel 57.5mm

I've never had an issue with a barrel not fitting my clarinet. This model, however, is too wide where the mouthpiece ought to go, and too tight where the rest of the clarinet body connects. Comparing it visually to my other barrels, one can clearly see the problem in the design. A whole millimeter off, and I can't use nor try it. I'm going to ask for a refund. The only dimensions specified were the length, not the width.
