This key cover is versatile and can fit most keys, regardless of their shape or size. Refer to the diagram to see which keys it works with. Unlike cheaper designs that use stretchy silicone, this cover is specially designed to stay securely in place without slipping or sliding. Made of durable and environmentally friendly silicone, it is soft and spongy, making it easier for individuals with arthritis or lupus to grip. The cover includes a label, eliminating the need for additional tags. The knobs on the key cap help indicate the correct orientation for inserting the key into the door. It's remarkable!
