Nylon cheese-sandwich bag protects toasters

Tastabags are re-usable nylon sandwich bags that you can put your cheese sandwiches into prior to heating them in a toaster oven; they keep the molten cheese from getting all over the place. Link (Thanks, Wiggly!)

Update: Rich sez, "these are for *toasters*, not toaster ovens, which makes them even neater. Just pop in your prepared grilled cheese, stick it vertically in the slot of a wide-slot toaster, and come back for your sandwich in a few minutes!"
