Very nice plates for an elevated luncheon. (Too nice for the average backyard BBQ.)The square dinner size plate is 1-2 inches smaller than the more common round disposable plates, but that didn't bother me--just makes it look like your have larger food helpings.They are sturdy and definitely reusable if you are inclined to wash them by hand. (Avoid putting them in the dishwasher.)Using them in the microwave probably is not officially recommended but would likely be okay for a under a minute and/or at a reduced power.I would certainly buy these again. Highly recommend!
