Lid Stuck? We can help! Whimsical and practical. That’s what Modgy’s new Silicon Jar openers are. In festive colors and fun prints, Modgy Silicone Jar Openers are made of 100% food grade super grippy Silicon. We have incorporated a grooved pattern on the underside for an even stronger grip. In addition to opening jars, they can double as a spatula/spoon rest, small hot pad/trivet and so on.
