These innovative, super-stretchy food-savers offer a reusable, safe alternative to plastic wrap. Constructed from a sticky rubber that offers five times the flexibility of silicone, CoverBlubbers stretch over plates, serving dishes and glassware as well as directly over many foods-perfect for saving that second half of grapefruit. Completely food safe, CoverBlubbers seal out air, will not transfer tastes and are BPA- and phthalate-free.
