|Made from hand blown borosilicate glass, the straws are safe to use with both hot and cold beverages. Unlike regular drinking straws that are often thrown out after one use, these can be enjoyed again and again. Simply wash clean with soap and water or give the inside of the tube a little scrub with a pipe cleaner for tougher cleaning jobs. The straws can be washed by hand or dishwasher. With just one sip, everyone will find themselves hooked! Each set has 2 and costs $25.00/set.
