Included with the K70 are a keypuller and a set of textured keycaps for WASD and 1-6.
An included wrist rest can be attached to the K70. The wrist rest is secured by sliding and snapping the tabs into the slots on the underside and can be removed by pinching the tabs.
Something not commonly seen is risers on all four corners as opposed to the usual two. This gives some more options for personal adjustment.
