Steel Series Qc K mass is a super thick mouse pad made from a high quality cloth material with a specially designed non-slip rubber base which prevents the pad from sliding; no matter what surface the mouse pad is placed on. This mouse pad features extremely heavy thickness which results in a very unique feeling. While the mouse pad is much more soft & comfortable to touch, the height is also fairly massive, reaching a total of 6mm. Other mouse pads from Steel Series are very thin, aiming to provide a high quality gaming surface, as close as possible to level of the tabletop it's used on.
