OnePlus makes plenty of accessories for its own phones, but starting now it also makes a case for a competing device — the iPhone 6s. The simple clip-on hard case brings the signature “sandstone” textured back found on the OnePlus One and 2 to your iPhone 6s or iPhone 6, along with a subtle OnePlus logo on the back and less subtle “Get a grip. #NeverSettle” message on the inside.

And nope, you don’t need an invite to purchase one, but when the case arrives you’ll find it contains an invite of its own, Giving you the ability to buy a OnePlus X if it turns out you aren’t happy with your iPhone experience. If you’re lucky, the invite will even let you purchase the limited edition ceramic OnePlus X. Going a step further, a very small number of cases will ship with a code to get a OnePlus X completely free.

The new sandstone iPhone 6s case from OnePlus will go on sale today from its online store for $19.99 — almost the same price you’ll pay for the other cases OnePlus sells for its own phones. The sandstone finish is nice and certainly adds grip to an otherwise slippery iPhone 6s, but we’re not sure how many iPhone owners will be turning to OnePlus for a case.

Whether it actually sells many of these is hardly the point, though — getting the OnePlus name and some OnePlus X invites out into the world is far more important. And I guess that’s what One plus is trying to do with this move. Would you get this cover for your IPhone 6 or 6s?…Comment below and Give Us your opinion about the IPhone cover by One plus.
