This Tupperware is such nice quality, it doesn’t feel cheap or flimsy or like it’s going to melt in the dishwasher like some of the cheaper ones that I get. I was surprised how secure the lid fit onto the base. It has the two flaps on the side to hold it down but also the rubber lining makes a tight seal with the body so you have to pull at it a bit to get it off. Awesome for any soups or saucy foods. And it’s lightweight!! This would definitely be the one that I would bring out with me to pack lunches and things. Also, the vent holes are really nice so I can stop using paper towels or paper plates to stop the splatter all over my microwave. I highly recommend!!
