The sharp stainless steel teeth will grip the lid firmly, as the soft, non-slip handle cushions your hand and absorbs pressure. The innovative base pad reduces the force required to open a jar by keeping the jar secure on the countertop. Simply place the non-slip base pad under the jar, slide the Jar Opener over the jar lid, and twist counter-clockwise to loosen the lid. The non-slip base pad securely attaches to the jar opener for storage. Dishwasher safe.
