HEY - I just had a thought!!!
Why make it a tupperware-party-STYLE thing? Why not actually integrate tupperware?
"And this stylish plastic cover will protect your liseuse while expressing your personality with butterflies and bright pink!" (scuse me while I go bleurrrrgh!)
"Get thirsty while reading? That's no longer a problem with the liseuse-n-juice! This handy drink bottle snaps right onto your liseuse cover for convenient slurping! And how about the larder-liseuse-n-juice, with a snap-on container for snacks?"
Some days I scare myself.
