When designing a donut box, prioritize durability and visual appeal. Use sturdy, eco-friendly materials like recycled cardboard to protect the donuts while being sustainable. The box should be grease-resistant and designed to keep the donuts fresh. A clear window on top can showcase the treats inside, enhancing the unboxing experience.

Bright, playful designs with bold colors or patterns can reflect the fun and indulgent nature of donuts. Clear branding with your logo and catchy phrases is essential for visibility. Additionally, the box should be easy to open and carry, balancing practicality with an inviting, attractive design.
