Inquiry (采购产品): sign board Iam looking for a greener alternative to making signs in our sign shop.Right now we use 4'x8'x1/4" foamcore, for signs on tradeshows and events,thrown away after a day or two. Do you carry a stiff cardboard in those dimensions? or any other alternatives? **** Hidden Message ***** richard egan 651 west tower Company: event productions inc.
