It comes with two lids, one which goes over the metal scale area and then a larger one that you then set the whole scale down into so that, between the one on top and the one on the bottom, the entire scale is enclosed and protected. It's also really handy that the top lid can be used to hold whatever it is you're measuring—just be sure to tare the scale after putting the lid down onto it—instead of putting your powdered supplements directly onto it. They can easily get into the cracks and crevices and be really annoying, so using the lid for this purpose is really handy. I've also used a small 2-inch by 2-inch piece of paper for that purpose too, as I can easily add powders to a bottle of water this way.
