Eco-Friendly, Vibrant Product Display Box Design

I need a packaging design for an eco-friendly product display box that will hold 2 of my products. The design should be minimalistic yet striking, using bright and vibrant colors.

Key requirements:
- Use of recycled cardboard as the primary material
- Incorporation of an eco-friendly design ethos
- Ability to create a design using bright and vibrant colors
- Understanding of minimalistic design principles
- Experience in product packaging design

Your creativity and understanding of eco-friendly design principles are key for this project. Please provide samples of your previous work in product packaging design, especially those that use recycled materials.

Please use your discretion to determine the most appropriate dimensions for the box.
