"Bonus packs from Accent, Sharpie and Expo brands all are featured on this custom, four-sided promotional unit developed for Staples.
The unusual shape of the central "tower" provides additional product space, and it helps to organize all of the product promoted. The lower section, furthermore, is divided into multiple bins, each designed for a different product. The display's large, colorful side panels clearly announce the brand names."
