These cases are extremely well made and do a wonderful job protecting beloved instruments for storage or during transit. The fact that they are well insulated means guiitars that go into the case in tune generally emerge in tune: swings in temperature and humidity outside the case seem to not affect the atmosphere captured within. I was so pleased with one that I acquired a little while ago that I have been slowly replacing various cases guitars came in with these wonderful cases from Hiscox. Excellent products, great customer service and relatively fast shipping. Highly recommended.
