Two "roll-up" banners. When extended they measure 2100mm tall by 810mm wide. They collapse into small(ish) metal boxes for transport
A more traditional system based on folding boards that take posters attached by "velcro". Each board measures 900mm high by 600mm wide. The headboard measures 250mm tall. The package folds down to the size of one board (900x600)
All units come in carry-cases.
