These silicone lids are Awesome! I've purchased this Lily Pad design many times, as well as their other designs of Hibiscus and Sunflower, for myself and friends & family and for co-workers too. Everyone LOVES them! They keep mugs & glasses covered for purity, freshness and temp, and will even suction onto a smooth-rimmed container if you gently push down on the topper! Chic and helpful = Great! Highly Recommend!!
