Two Myriad Right Angle Ergonomic Keyboard and mouse pad with value swivel articulating arm and gel palm support.
Two with articulating but not sliding arm.
Well over $1000 new.
They've just been lying around unused for a few years and something has been laying against them for a while so there are dents in the gel pads that should come out over time or maybe with a heat gun.
For more info on them.
