Use the Dotz silicone stretch tops to keep fresh salads or leftovers in the fridge for longer. No more fiddling with expensive plastic film to seal a bowl completely. These lids can be reused endlessly and then simply cleaned in the dishwasher, they are also microwave-proof. Not only will you save money, but your plastic waste will also be a lot smaller. The lids are made of high-quality food-safe silicone and are completely phthalate- and BPA-free. They are very flexible and fit easily over almost all your plates, bowls or cups. They adapt to the shape of your bowl. The lids barely take up any space in your drawer when you are not using them. Unlike disposable plastic film, the lids allow you to seal your bowl hermetically to keep a can of soup or a jug of fruit juice leakproof in your fridge. Place the lid on your jug and press the top of the lid to push the air out. The silicone rim will fit nicely around your jug and will not let any air through. You can use the lids to take your salad to work without leaving any leftovers in your bag. The perfect tool to reduce food waste!
