Yes, we admit it, sometimes those jar lids get a bit tight. The fat can "set" inside the threads and make getting to your wonderful fat take longer than you hoped. Anything that delays you from getting your fat is a bad, bad thing. That's when it's time to use the Grip it and Lipid jar grip! Also, this jar opener gripper makes a nice coaster or a really bad Frisbee. *Jar not included- it's there to show you scale.
