This is a knob with a base purchased from a country雑貨 store. I tried to replace a knob once, but the size didn't fit, so I've been storing it at home since then. The knob is a set and has a cute heart pattern. It's a round knob with a diameter of 3.7cm and a height of 3cm. The wooden base is about 7cm; the base can be removed. Please check the photos. The base and screws will be sent as shown in the photos. If the screw length doesn't fit, please purchase screws that suit your needs.
