Moisture is the number one threat to chocolate as it affects the taste texture and shelf life.
Paper boxes for the average chocolate bar do not keep out moisture or bacteria, even if there are no air gaps in the corners and flip seals.
Plastic wrap aka cello aka shrink wrap can keep out moisture, but are not as healthy or environmentally friendly and can easily tear.
Wax is biodegradable and is edible in small quantities.
Since the packaging is sustainable, it will hold up under the sun and remain food safe. The nutrients can diminish after durations of intense heat.
If not immediately consumed, refrigeration is recommended (33-40°F).
Additionally, the Chocolate Wheel can rest on all sides. Since it's Biodegradable and has a dynamic structure, it promotes an ideal pocket-sized product.
