Vibrant Cardboard Counter Display Design

I need a small, cardboard counter display unit created from scratch, complete with a full tech pack that a printer can take straight to production. The unit must be vibrant and colourful to grab attention at first glance, but it also has to solve three functional challenges: • Product insert: the inner structure must hold each item perfectly upright, even on a busy till counter. • Eye-catching header: the top/back panel should act like a mini billboard, clearly explaining the product to first-time shoppers. • Tester holder: work in a dedicated spot for a tester with the printed prompt “Tester / Twist me open.” Practicalities matter as much as looks. The design should flat-pack efficiently so retailers can ship or store it with individual units nested inside the outer carton. Please include dielines, material call-outs, print layers, assembly steps, and any suggested finishes or coatings that keep the colours punchy without compromising budget. If you have experience engineering small POS displays from corrugated or solid board and can translate creative ideas into precise manufacturing files, I’d love to see how you’d tackle this.
