According to Apple’s website, “Designed by Apple to complement your iPhone, the form of the silicone case fits snugly over the volume buttons, side button, and curves of your device without adding bulk. A soft microfiber lining on the inside helps protect your iPhone. On the outside, the silky, soft-touch finish of the silicone exterior feels great in your hand.”
This case was purchased to protect my iPhone 7 Plus in Jet Black (the gloss black version of the iPhone 7 Plus). The same case also fit the next “Plus” iPhone, the iPhone 8 Plus, and Apple began to refer to the product as the iPhone 8 Plus/7 Plus Silicone Case.
The case was released in Midnight Blue, Pink Sand, Sea Blue, Black, Cocoa, Ocean Blue, Denim Blue, (PRODUCT)RED, Stone, and White.
