Our Stainless Steel SUS316L Straws are made in Taiwan using medical grade Japanese SUS316L stainless steel. Each straw contains 18% chromium, 10% nickel and 2% molybdenum and are more resistant against acid and corrosion than our SUS304 stainless steel straws. The straws have passed the SGS certification lead test, SGS Germany 3% acetic acid metal dissolution test and tested negative for SGS radiation detection. Our stainless steel straws are reusable and have undergone rigorous testing to ensure they can last forever. By using one of our reusable straws, you are contributing to less plastic waste into the environment. The straws are made without sharp edges, so they are suitable for use by all ages including children.
If not specially and carefully treated, stainless steel may leak toxic and dangerous substances and endanger your health. Our straws are treated and processed using medical methods and never made using recycled materials, so they are safe and sanitary. The inner and outer surfaces of the stainless steel straws have undergone electro polishing to remove unwanted materials as well as medically safe passivation to prevent corrosion (acid resistance). They have been ground and polished to allow for easy cleaning and the prevention of any adhesion, and sterilized at high temperatures to remove toxic materials.
Each SUS304 straw is marked with 3 rings on top and 3 rings at the bottom, while SUS316L straw is marked with 3 rings on top and 6 rings at the bottom.
