"His" and "hers" mice for the criminally insane

We're not going to lie to you: we have no idea what the crap is going on here. From what we can glean, these two artifacts are both mice, of the computer variety, with various glitter, glam and appendages to denote "his" (warudekomausu) and "hers" (kawadekomausu) editions. What we can't figure out is why anyone would ever buy one of these. No matter, it won't be our 12,600 yen (about $109 US) down the drain.
