• 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 out of 100% food grade super grippy Silicon. We have incorporated a grooved pattern on the underside for even stronger grip. In addition to opening jars they can double as a spatula/spoon rest, small hot pad/trivet and so on.
