This combo combines a 3rd party Smart Cover with unique Secure Lock Design snap-on back clear Polycarbonate cover that firmly covers and secures the smart cover in place. The back cover slightly extends and covers the metal strip on the smart cover so it locks the smart cover in place. It doesn't in any way effect the folding of the smart cover. This combination gives your New iPad (aka iPad 3) or iPad 2 a sleek and secure full body protection. The Smart Cover enables the sleep/wake function of the New iPad 3 or iPad 2, and can also be folded back into a stand to prop the new iPad 3 or iPad 2 in either horizontal or vertical viewing position. Compatible with iPad 2 and The New iPad 3 only, they do NOT fit the first generation iPad 1. Please put on the smart cover first, then simply snap on the back case, and it connects/locks the smart cover in place securely. Please note the smart case cover included in this item is made by 3rd party company, not made by Apple.
