Minimalist Coaster Packaging Design

I'm seeking a packaging designer to create modern, ocean/seaweed theme minimalistic packaging for coasters made of sustainable concrete from the seashells. The packaging should be made from cardboard, highlighting sustainability without compromising style. It should be simple with kelp or ocean on the top of the cardboard. The packaging is ideally of following size 305x215x12mm to fit in an envelope for delivery.

Ideal Skills and Experience:
- Expertise in cardboard packaging design
- Portfolio in modern and minimalistic designs
- Experience designing for homeware products, specifically coasters
- Sustainability-focused design philosophy
