For anyone who struggles to open jars, this is the gadget for you. The jar opener comes with its own base pad. Place the jar on the pad, position the opener tooth-edge on the edge of the lid and twist counter-clockwise to open. The teeth are gentle yet strong and grip the lid while you push on the soft grip handle. The base pad helps to hold the jar in place while you push, and secures to the opener so it doesn't disappear in the gadget drawer. 9"/23cm Dishwasher safe.
