One-year renewable grass - reed as an eco-friendly alternative to plastic and paper straws. Straws are made of reed stems - 100% plant-based materials. They are biodegradable and compostable. As far as you use only plant material, you can move closer to the 0-waste concept of living with these straws. The straws decompose in a few months and leave no toxic traces at all.
