Smart 15mm diameter mixer-style control knob from Rean with black knob body, white marker line and a blue coloured insert and skirt which offers a crisp, attractive appearance.
Superb plastic moulding quality for years now, Lovely shade of blue, IMO the best feeling hard plastic knobs money can buy for potentiometers and rotary switches. I have personally used over 1000 in professional products over the years !
