Each straw comes with a reusable cleaning brush making them easy to clean and they are also dishwasher safe. Our glass straws are handmade with love and inspected for quality. They also have a lifetime guarantee! Don't worry about the breakage because we have you and your customers taken care of. We have been making glass straws for over 15 years and we stand behind our product no matter the breakage. Less than 2% REPLACED and your customers come to us for it. The Everyday straw is our Classic Restaurant 9.5 mm in diameter and 8 inches in length. If you want different lengths or diameters we have that. 6.25 inches- coffee, cocktail, small glass 8-10 oz 8 inches- standard straw size, travel straw 12-24 oz 10 inches- long, for 30 oz cups Glass Straws are great for hot beverages since glass is an insulator (protecting your lips) whereas a stainless steel straw with a hot beverage could burn your lips. These are great gifts for any occasion! They are unique and functional as well as helping reducing single use plastic.
