To a toddler, "Don't touch the stove" sounds a lot like "Please touch the stove immediately."
Jool Baby Stove Knob Covers fit over your stove's control knobs so small hands can't turn on a burner. They also stop the cat, the dog, and your own hip when you lean on the counter. The covers are clear, so you can check whether a burner is on without opening anything.
They fit knobs less than 1.5" tall and less than 2.25" in diameter, spaced more than 3" apart, which covers most standard stoves. They install without tools and now include adhesive to help hold them in place. Easy for you to open. Hard for your toddler to figure out. Five covers per pack.
