Cardboard Box Design Needed

I’m looking for a clean, production-ready design for a cardboard box. The size, shape, and graphics are still flexible, but the final artwork must be optimised for cardboard printing and die-cutting.

Here’s what I need from you:
• A precise dieline with bleed, fold, and cut marks ready for the printer
• High-resolution artwork in CMYK (Adobe Illustrator or PDF)
• A simple 3D mock-up so I can preview how the box will look once assembled

Feel free to suggest structural or visual ideas that add practicality and shelf appeal—I haven’t locked down a definitive style yet, so your creativity will drive the final look. Let me know your timeline and any similar packaging you’ve designed so I can gauge fit quickly.
