This is a Christina violin case. It has a dial lock. Color: Gray Black Size: For full-size violins Lock type: Dial lock Material: Hard case Accessories: Music sheet holder Country of manufacture: China I bought this online a while ago, looking for an affordable hard case. I liked that it had a lock, but when I actually held it, I found that the music sheet holder couldn't be removed, and I was a little worried about how well it would protect the instrument, so I'm selling it! This is suitable for those who have started playing the violin as a hobby and are looking for a decent-looking case, or for storing junk items, etc.
