Gewa Air 2.1 Violincase 4/4 WH/SH

I received this case and my 36.1 cm violin would not fit in by a long way, even without a protective sleeve. I measured the possible body length in the case I was sent - it was 35.5 cms. I tried 2 other violins - one @ 36 cms and one @ 35cms. Only the 35cms comfortably fitted - this is almost 7/8 size. I could not get the 36cms one in a with a silk sleeve without possibly forcing it in. Very disappointing.
I have never had this problem in 35 yrs as a professional player. Why do Gewa not have a more generous length for this lightweight case? (They have a adjustable version in their heavier cases).
The star system doesn't really cover my problem - so I give it 2*. There's nothing wrong with the manufacture except the sizing.
Thomann efficiently sent me an email for return for which I am grateful.
