Simple but effective, the Avanti Jar Opener opens stubborn vacuum lids on jars and bottles with ease. Made from tough, durable ABS plastic, this jar opener is so easy-to-use. Just place against the lid of the jar. Lift ever-so-slightly, to release the vacuum which will cause the lid to pop. The lid can now be easily unscrewed. This handy tool does not damage the lid, which can still be used to reseal the jar or bottle.
