A set of four wide stainless steel straws. Measures 8. 5 inches long each with a 5mm opening. Fits most tumblers, including the YETI tumbler. Our original Stainless Steel Drink Straws reintroduced us all to the flavor and fun of this vintage design. Soda never tasted better than through a stainless steel straw and this continues to be true today. Reduce your plastic footprint on our planet by using these 8. 5 inch long, polished stainless steel wide drink straws. Made of superior quality 18-8 stainless steel that is durable, scratch and rust-resistant, unbendable and unbreakable. Our straws are dishwasher safe but for a more thorough cleaning use a pipe cleaner with soap and water.
