Reusable storage lids made from high quality, food grade silicone. Use instead of plastic wrap to cover almost any dish, bowl or plate with a more secure cover. Each set includes six different sizes, and with the combination, you will be able to cover things ranging from 2.75" - 10". It doesn't matter if they are round, square, oblong or rectangle because the versatile design allows these lids to stretch to any shape and still provide an airtight seal. The sturdy material is completely washable and reusable, and it is so strong that it actually provides a stack-able surface once in place. Convenient tabs along the outside edge provide handles for easy placement, and the material remains non-slip on metal, glass, plastic and other surfaces, so once in place they won't slide or fall off. Save the second half of a soda for later on, or seal an open pet food can to use the next day. Cover watermelon and cantaloupe for a simple and effective way to store the other half, or save leftovers from dinner without making the fridge stink. These are faster, stronger, cheaper and more effective than flimsy plastic film, and they are also perfect for replacing lost lids, or ones that cause annoyance. Dishwasher, oven, freezer and microwave safe.
