I first started out using C and A 10mm twin-wall to make DJ Soundmachines! but that's another story. Along the way I realised 4mm polycarbonate was also ideal for displays and exhibitions. Light and strong it makes an ideal display panel base upon which to spray-mount printed material. Hinged with Gafa tape they fold down flat to virtually nothing and even pack away in the original box to be transported to the next venue. As an independent board game manufacturer space is at a premium but the panels take up no room and even add to the experience of my Funpack Games Showroom.
