Our 18/8 stainless steel products are durable, reusable, and resist oxidation and corrosion.  Just like our glass straws, we offer a lifetime guarantee on our stainless steel straws against breakage. Both our lids and straws are easy to clean (dishwasher safe). Our lids feature a patented spill resistant grommet and sealing ring made from 100% silicone.
