OnePlus is today launching a new smartphone case with its signature Sandstone finish — but it isn’t compatible with any of the company’s own devices. Instead, it’s made for iPhone 6 and iPhone 6s, and we love it!

Check out our hands-on gallery below.

Thanks to that Sandstone finish, which is only available in black for now, the OnePlus case for iPhone has plenty of grip. It also looks great (though it would look even better on a space gray iPhone), is incredibly robust, and doesn’t add to much bulk to your device.

Here’s the full gallery. Click the pictures to view them at full size.

The OnePlus case for iPhone is priced at $19.99 in the U.S., £15.99 in the U.K., and €19.99 in Europe — and you can orders yours now from the OnePlus online store soon. You won’t just get the case, either: Inside every box is an invite that lets you buy a OnePlus X.

Despite being the most affordable option in the OnePlus lineup, the OnePlus X delivers premium design and great specifications. It starts at $249 for the “Onyx” model made out of glass, but there’s also a limited-edition ceramic model available in Europe.

Your invite will let you buy one of these devices, and if you’re really lucky, you won’t have to pay a penny for it. You can also get the same Sandstone case for the new OnePlus X now.
