Signwaves has added a new A0 size Sentinel poster unit to fill the size gap between its existing 30" x 40" and 40" x 60" Sentinels. The company says some of the biggest names in retail use Sentinel to be their ’silent salesman’. Product design manager at Signwaves, Simon Harvey, says: "Having done several ’custom’ design projects for customers wanting a high-spec A0 poster sign, introducing a standard option was the next logical step. With six years solid service, Sentinel has proved itself to be an extremely powerful promotional tool. And now with three standard sizes to choose from, we’re very confident Sentinel can help even more brands and retailers drive footfall and sales in store."
