The Gewa Air 3.9 Cello Case is a great piece of kit. It is sturdy, stable and robust whilst being surprisingly lightweight and easy to handle at only 3.9kg. The case closes and locks very easily and the lining and internal fixtures are well designed and of good quality. The customer service was also excellent and the case was delivered very swiftly and in perfect condition via UPS. I am really pleased with the product and the customer experience. Thank you, Thomann!
