The best silicone lids invented. It actually save me on using seran wrap and helps the environment. It comes in 12 different sizes. I have used on my water cup on the go, used to save half of my cut apple, used on my left over dinner, and used it on can food.The silicone lids is really useful and easy to put on. It save time and money. It does't leak either. The silicone lids stay on tight. Unlike seran wrap that can spill and make mess. These lids are secured and spill proof. I would highly recommended to get this for yourself or a gift. I would not mind getting another pack. #rankboosterreview #sponsored #hxpever
