Traditional polystyrene packing peanuts are notorious environmental hazards. Cornstarch packing peanuts are a 100% plant-based, non-toxic alternative:

### How They Work:

Manufactured from expanded plant starch (derived from corn, potato, or wheat).

100% Water-Soluble: When held under running warm water in a sink, they dissolve completely in seconds into harmless plant starches.

Static-Free: Will not cling stubbornly to clothing, pet fur, or electronics.

Ocean Safe: If discarded, they dissolve rapidly in rainfall and seawater without harming marine wildlife.
