These beautiful reusable metal straws are perfectly sized for pint Mason jars! They work best for cocktails, water, juice, iced tea, coffee, soda, etc. We recommend buying a thin straw cleaner, but they are also dishwasher safe. Our 7.5″ long, 6mm outside diameter (5mm inside diameter) straws have a 45° bend for drinking comfort (and bonus style points!). The engraved threading gives them that nostalgic plastic bendy straw look, but they do not bend. They are the perfect height for a pint (16oz) jar or 12oz jelly jar. Pint jars are ideal for almost any kind of drink! Keep your family safe from chemical leach and serve your refreshments or mixed drinks in style! They fit in almost any straw hole lid (even daisy lids) and are perfect for drinking water, juice, iced tea, coffee, soda, etc.
