Each straw contains 18% chromium and 8% nickel and are resistant against acid and corrosion. The straws also passed the SGS certification lead test, SGS Germany 3% acetic acid metal dissolution test and tested negative for SGS radiation detection. By using one of our reusable stainless steel 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.
