-The lid can be used for storing food in the fridge and to heat food in the microwave or oven.
"IKEA has done it all, from smart wardrobes to practical jars - a tradition of good storage that we wanted to continue to develop. We were inspired by Japanese bento boxes when we designed a series of oven/serving dishes in glass. IKEA PS 2012 oven/serving dishes can be stacked inside one another or placed side by side and take little space in a cabinet. You can use them in the oven, serve food in them, put what's left over in the fridge and warm it in the microwave - all in the same dishes. Transparent dishes make it easy to see what food you have at home and encourage you to eat leftovers."
