C. Robert Hopf Akkordzither Case 100/3-4

First impression is that it appears to be cheap plastic! Closer examination and feeling the weight reveals that it is wooden with a waterproof washable covering (Not unlike Tolex on Fender cases). The inside has a pleasantly soft red velvet like material. If you consider the real purpose - To effectively protect your instrument, then this is far more sturdy than a soft zip up bag. Stronger if you don't mind the extra weight. If the charcoal black finish doesn't put you off, then it's the best choice available...Unfortunately when closing the case for the very first time the side catch on the left failed to align properly. This resulted in the screws ripping out from the wood! I will now drill through the wood and fit small nuts and bolts rather than the wood screws which were not robust enough for the job!
