chinese take out: It all depends on how old the microwave is. The older ones (older than 8 years) will probably do damage, but the newer ones will not. They have been updated to handle some metal parts without doing damage.|||No. Metal should not be put in the microwave. Either remove the handles, or put the food on a plate. Be sure to stir during the cooking time, or the food near the outside of the box will burn, and the food in the middle will still be cold. Enjoy! :-))|||thats BIG heck no buddy an waful burning smell will start to come out of your microwave and will probably linger for quite a while and you might start a fire and the paper in the cardboard tens to puul moisture form the food so you end up with 1 large peice of crud that soemwhat resembles a brick. just put your left overs on a plate|||yes you shore can! thats only if you have a new micro wave! also make shore you stirr the food! Have fun!!!!!!
