This clever Microwave Plate Cover collapses to just 3mm for space saving storage and pops up easily for you to use. The perforations on the top allow steam to escape, while keeping your microwave free from splashes and mess. Turn it upside down and you can use it as a colander or strainer. The large 10.5? size fits most plates and bowls. The cover measures 10.5 inches in diameter and 3.5 inches tall when expanded and collapses down to 1 inch. BPA free and dishwasher safe for easy cleaning.
