These are awesome! Everything you could want in a reusable straw! The rubber tip is great because many other straws are uncomfortably too large in diameter and this make sipping enjoyable. It's great to have a plastic case for it in case you can't wash your straw right away you can simply put it away and wash when you get home. The clip is great! I keep one clipped to the side of my purse all the time. And as usual, anypromo always does a great job and delivers on time!
