I love how simple and yet effective this idea is. I sometimes struggle to open jars, especially if my hands are wet (from cooking). Sometimes the jar is slippery, which makes it hard to open. This tool solves this issue. First, there’s a plastic base bad that you place under the jar that solves one of the problems - it is a simple piece of plastic and yet it is able to hold the jar in place without slipping. That alone solves the issue 50% of the time. But if you still can’t open the jar, the actual tool is a metal piece that you can place on top of the lid and it can “grab” the lid so you can twist it. It may end up causing some damage to the lid (since one of the sides has indentations to actually “grab” the lid), but you should be able to open any jar in seconds, no matter how tight it is closed. This is my new best friend when cooking. I’m in love.
