These switchplates are handmade to fit all standard North American electrical covers. They are ceramic and sturdy but please take a few pre-cautions.
Do not over tighten the screws when you install them. Our ceramic is sturdy but it can crack. We provide complimentary nice looking off-white nylon screws with each switch plate cover. They look good and do not scratch the artwork!
When cleaning use a mild soap and warm water. Avoid anything abrasive on the switch plates as it will scratch the surface.
