Specifically made for the drop alt keyboard is still compatible for 60 & 65 percent keyboards and there is a hidden compartment in the inside to bring along a small cable, overall recommend for those wanting a case to protect the keyboard from dust and MAYBE to bring on the go but not the greatest protection.
I'm using this with a Bakenoko65 with MT3 keycaps and it fits perfectly; nice and snug and not so tight that it's hard to get it in all the way. Because of the sculpted keycaps there's even space in the inside pouch for a cable, keycap puller, or whatever other small tools you may want to throw in the case. Was using the giant hard case that Cannonkeys sent with the keyboard (it's larger than a 75% hard case) and it's a huge upgrade going to this one and having more room in my work bag.
I bought this case for my ALT keyboard and it fits veeery exactly, the cable space feels a bit too reduced for a big one, and even a small cable fits very snugly, but what counts is that it does protect the keyboard.
I tried to use this with a Finalkey v65 but it was a little too short and the flap did not fully close. It's a shame because other than that, the case is nice.
