Medium Safer Rounded End Stainless Steel Metal Straws for Pint Mason Jars, Medium Cups, or Pint Glasses, 4 Pack + Cleaning BrushCategory: Canning Jar Cleaning BrushThese medium, stainless steel straws are the best metal straws you can buy for regular mouth and wide mouth pint Mason jars, but they also work great for pint glasses and other similarly sized cups.Our 7 1/4" long, 8mm outside diameter stainless steel straws fit in most Mason Jar Lifestyle straw hole tumbler lids and are perfect for drinking any beverage. The 6.2mm internal diameter is a great all-purpose size. They work well for water, juice, iced tea, coffee, or soda, as well as thicker liquids like smoothies, yogurt, milk shakes, frozen cocktails, or protein shakes.The 10.5mm locking tab near the end will hold the straw in the straw hole lids. Put the straw in the jar first, then put the lid over the top and screw it on. This is great for kids who pull their straws out and cant get them back in, and if the drink gets tipped over the straw stays in the jar.The rounded ends are noticeably less sharp and more comfortable in your mouth, and they are safer in the event you accidentally poke yourself!
