These 10 Inch drinking straws are an excellent choice for both normal beverage consumption and drinking on the go. Made to be tall enough for use with 30 oz tumblers, these straws are tall enough for most cups. At a diameter of 0.28 inches, they are exceptionally easy to drink from. This also makes them suitable for smoothies. However, milkshakes and other very thick drinks are best consumed with 0.31 inch and larger straws. These straws are made from high quality polypropylene (PP) and will not buckle inwards or spring leaks during normal use. Perfect for home use, concession stands, bars, parties, and more!
