Looking for coffin case guitar

A fried o mine gave me an guitar as a present for our 10 years of friendship. But as much I would like to take care of it, I can seems to be. Because our home is kinda messy right now and a lot of fixing i happening hence I really cant make it safe even to my own room. But Ive heard that coffin case guitar is a best way to secure the guitar specially that metal case but am looking for at least wooden if that have it so. Let me know if you have any on sale or knew someone who sells it, I’ll probably buy it but I hope in a very reasonable price..
