On the heels of its GLAS.t Slim for iPhone 5, Spigen SGP has now released GLAS.tR Slim ($35). Whereas the original has angled edges, this glass screen protector's edges are rounded for a greater resistance to chipping and a more comfortable feel. The "slim" in the name refers to the fact that it's only 0.4mm thick. In the box, you get film for the back of your iPhone, an alcohol wipe, cleaning cloth, squeegee, and a set of Home Button stickers.
