GUANCI 8 Pack Silicone Lids for Bowl Silicone Microwave Cover

The vacuum suction function is not present in the GUANCI silicone lids set. Kindly note this.As you can see from the related blog post, our silicone lids can be vacuum-sucked, but only under certain circumstances. These include a smooth container mouth, a container that is smaller than our silicone lid, and expert operation. It’s not a problem with our silicone lids, so it’s okay if you can’t use the vacuum suction feature.Food-grade and heat and cold resistance are the primary functions of our silicone covers.
