Gator GC-Semi-hollow Guitar ABS Case

This sturdy ABS case fits my Epiphone Dot like a glove. The interior is well padded with soft plush material.
There is however one problem. The lid doesn't always stay open by itself so it fell close on my guitar several times when taking the guitar in or out. The edges are aluminium so it is easy to damage the guitar when it falls shut.
The case is also very bulky. On the outside it looks like it could hold a full size acoustic guitar. I'd prefer it a bit slimmer.
