I got my case today. It's just a plain black one with magnets.
It fits well, not perfect, it's a very slight bit loose but otherwise it's good enough. I suspect the reason for this is because I'm using low profile DSA keycaps.
The material is really tough though. I'm still wondering how something can be this stiff, which is really good. It's nice and tough and inside is still soft enough to keep it padded.
There's enough space at the end to keep a cable and I really like the feel of the magnets.
Overall I'd say it's a very good case and I intend to buy another one. Just make sure to check your dimensions with him first when you buy a premade one to make sure it fits nicely
Looking forward to the return of the custom round!
