Wheat straws are made from natural wheat stems and are 100% biodegradable. They are the byproduct of wheat production. Once the wheat plant reaches maturity and turns golden yellow, the grain is harvested off. The wheat stems get cut into drink sized lengths. The outer diameter is from 4-6mm and the length can be made 130-200mm. No two straws are ever the same, because of naturally occurring variance in the wheat plant. Our straws then go through a rinsing process to remove any speck of dirt, or even insects. The straws are soaked and rinsed three times with sterilized water to ensure hygiene.
