There are a couple of good quality flipcovers available for your Moto X Play device. I would wish to add a cover that is interesting enough to the above list.
Official Motorola Moto X Play Flip Shell Cover
It would be an expensive proposition for most of us, yet it would be worth mentioning for the people who are interested. Priced at Rs. 2544.99, you can buy it in Black color. It is available at this link - http://in.mobilefun.com/54633-official-motorola-moto-x-play-flip-shell-cover-black.html
