This is Knobbles and Bobbles' unusual resin shaped knob... with bunny ears! Please note this black design will complement the other bunny knobs, but is not identical in shape or size as the others. This has a flatter shape, not round. The widest part of this knob is approximately 55m - outside ear to outside ear. The knob itself is approx 35mm diameter. The bolt will at least fit through a door that is up to 2.5cm thick. Each knob is supplied with the knob itself and metal fixings including bolts and washers. Any questions?
