Bought something very similar :
Amazon.com: CoverON® Slim Hard Case for Nokia Lumia 1520 with Cover Removal Tool - (Black Carbon Fiber): Cell Phones & Accessories
... got it, yesterday. As mentioned, feels very good in the hand, conforms to the phone, raises both screen & camera lens off a hard surface. Feels like a second skin on the phone, primarily got it to add
grip.
Also, it replaced the case that came with this :
Black Hard Case Cover Belt Clip Face in Out Holster for Nokia Lumia 1520 Phone | eBay
... which did NOT feel very good in the hand. To my surprise (I hoped), the new case fit very well (very snug, like it was made for it) in the old holster - because sometimes pockets are not an option.
Cost me nothing, I applied my Bing search points against 2 Amazon $5. gift cards. Would purchase the case again, 2 pieces of plastic which snap together - skinned with a muted Carbon Fiber pattern. Solution is perfect for my needs.
