Button Mini: handy and functional You can place this lamp everywhere you want thanks to its different sizes produced by Flos (Button, diameter 41 cm; Mini Button, diameter 14 cm; Button HL, diameter 47 cm). A little light button: the look doesn’t deceive, because Button is just the way it shows itself, that is a circular diffuser made up of polycarbonate (injection molding process) with a faint opaline level and a closing screw on the center (which also supports the diffuser) made up of burnished aluminum alloy. In order to allow Button to be placed also outside – so to resist to the bad weather – it has been equipped with weather strip for dust and water.
