Try a glass drinking straw to save our seas! These sets of 6 eco-friendly drinking straws are handmade of durable Duran Schott and Simax Borosilicate (eg. Pyrex) glass, which is better quality than what you will find in China (on eg. Amazon or Ebay) and we are right here in Eugene, Oregon. These straws are high quality, durable glass. Borosilicate glass is harder than regular bottles and glasses, besides that, all of our straws are properly kiln annealed. With normal use, they can last a lifetime.
