Good quality zip, lightweight with comfy shoulder straps.
Fits for standard 1/2 violin (a bit tight for our luthier made violin though), neck of the violin does not touch the bottom of the case which is very nice, we put an extra sponge pad under the neck-body part for extra protection and works wonders.
Rosin and shoulder rest (KUN) can fit inside the case without any trouble.
Sheet music will need separate folder since this is a triangle shaped case.
