This is a great telescoping straw that you can use, clean with accompanying brush and then put back in its protective case and carry with you or put back in a drawer ready for use again and again. It is well made and even has a silicone piece at the top that you actually put your mouth on to suck so you don’t actually put your mouth on any metal piece that some may find uncomfortable. It unfolds to nine inches so can be very accommodating to whatever glass you might be wanting to use it with. The brush is a nice tight fit inside the straw so using it briskly under hot soap and water will quickly clean the inside of your straw so no worries about bacteria. The case has a push on cap that is easy to pull off or push on. To store you simply push the straw closed, push the cleaning brush into the straw and put the folded straw and brush into the container and put on the cap. It is just as simple to use the straw following these instructions in reverse. This is BPA free and can also be used on the upper rack of a dishwasher if you like. It is a great price to get one for each family member to use which helps keep plastic straws out of of landfills.
