Minimalism isn't in ROG's profile, and I'm pretty sure it never will be—of course, this isn't a problem. The package is quite crowded with render images, graphics textures, and the usual marketing text and technical specifications. There's also a window that is held in place by a patch of surprisingly strong Velcro. Once the box is opened, you can access the Gladius II Wireless mouse, and there are quite a few included accessories. There's a padded carry-pouch, ROG sticker, set of Omron D2F-01F switches, quick-start guide, and of course, the charging cable and USB dongle.
Shape
The Gladius II Wireless features the exact same shape and materials as the previous models of the line. This means it has a rather big, high profile and is mainly built for right-handed palm grippers, albeit grip style is a matter of personal preference, and the mouse can be used however you like.
As for the shell design, it's not a subtle or minimalist rodent—again, just what would you expect from a ROG product. The left side is curved inward both horizontally and vertically to help maintain a stable grip even when picking up the mouse. For the same reason, the right slide is slanted and features some inward curves at the front. Both main buttons have some well-defined comfort grooves to help your fingers get into a comfortable position.
Now for measurements: the Gladius II Wireless is 126 mm (5.19") long, which is pretty much average. The total width is 67 mm (2.72"), but depending on your grip style, the actual width at which it is gripped is approximately 56 mm (2.20"). The total height is 45 mm (1.77"), and the hump is centered. With these dimensions, I would mainly recommend this mouse to palm grippers with hands bigger than 17 cm. However, it can work with smaller hands and different grip styles as well and is, as such, all up to personal preference—my recommendations are just basic guidelines.
