Wow very nice artisan wristrest, when I get one I'll be sure to proudly let everyone know "I GOT THE CLAP".
Now for some real feedback: I can't see any easy way to remove the lid ("PC cap"). It seems like when it's in palce it'd be hard to remove without a suction cup or turning the wrist rest upside down (and therefore potentially scattering your priceless resin). Other lidded cases implement tabs in their lid that allow you to get some grip to lift them up, see the Naptime if you want an excellent example.
