Review on 🔧 2021 Silicone Belt Jar Opener - Adjustable Wrench for Opening Extra Small (3/8") to Extra Large (6") Bottle Caps. Universal Kitchen Tool for Replacing Water Filter Cartridges and Opening Spice Lids. by David Dortch

This key removes the large lid. It's better if someone holds the glass underneath while you do this. You can't do this alone unless you have four arms. Much easier to use if you buy a small metal device that's just there to break the seal on the lid first. The vacuum seal makes it very difficult to remove the cover. Again this does what I expected but you need another person to help or buy two of these. One of them should be large enough to cover the diameter of the entire can.
