Want to protect a 12-inch MacBook without bulk? The Mosiso snap-on hard case and matching keyboard cover cost me about $16 for the set.
I bought mine in wine (other colors are available) for my 2015 12-inch MacBook, the smallest of the lineup. Here’s the unboxing, how the two halves snap on, what’s left open, and how well that silicone keyboard cover actually stays put.
- Snaps on easily with a good fit
- Soft-touch finish that doesn’t show fingerprints
- No Apple logo cutout keeps a clean look
- Headphone jack, mics and USB-C left open
- Keyboard cover stays put better than expected
- Bottom shell is a tight fit to get over the lip
- Keyboard cover keeps the lid from closing quite as far
- Slightly translucent, so some light shows through

Unboxing
It came shrink-wrapped, and then each piece was wrapped in plastic again. They really make sure it gets to you in pristine condition.
There’s no cutout for the Apple logo, which I actually prefer: nothing gets in and it keeps a streamlined look. The shell is a little translucent, so you get a bit of light play through it. The silicone feet come already installed, and there are spares in the box.

Installing the top and bottom
The top has tabs near the front edge and tabs set in at the back so it clears the hinge. Snap it all on and the top clicks down with a nice fit all the way around. Easy.
The bottom is notched where the clamshell opens, with a little thumb notch too. Clip the front first, then lift and clip the back and sides over the lip. It’s definitely a tight fit, but I got it on.

What’s covered and what’s open
The edges by the ports are open, so the headphone jack, the microphone openings and the USB-C port are all available. The bottom has vent slits even though the MacBook itself is sealed, I think to help heat radiate out, since MacBooks get hot.
The finish is matte, like soft-touch plastic, and it doesn’t show fingerprints, which is nice.

The keyboard cover surprised me
I wasn’t sure the silicone keyboard cover would stay on by itself. It’ll peel right off if you pull it, but it doesn’t slide around. Even with the laptop held past vertical, it stays put. Turned fully upside down, it slowly falls off.
It finishes off the color nicely. The one tradeoff is the lid doesn’t close quite as far with it on. Overall, I’m pretty impressed.
