The knobs are made of wood. Each is painted and decoupaged with high quality art prints taken from my own original art, painted by me. Each one is coated in a layer of high gloss sealer, then a high gloss medium us used on the front of each that covers them more than 100 coats of sealer could. This makes the designs very durable.
The size of each knob: 1.5 inches/38.3mmy in diameter and attach easily with a screw (included).
Need more than 1 knob or set? Contact me and I will make a custom listing especially for you.
