It's an oppai mousepad. No, that's not an accurate name.

It's one of those mousepads with a wrist-rest. It's quite ergonomic, takes a lot of strain off your wrist when mousing around.

But whatever. Why not spice things up a little. A little lower than the 'oppai'.

I'm pretty sure it's one of those '3 Dimensional' mousepads. I could very well be wrong, the picture isn't very good IMO (not that I was looking for too long >.>)
