I am a big fan of reusable straws and I really love these. The capsules are such a great way to carry them and keep them (and your bag) clean. Each capsule has a “squeegee” in it to clean the straw. I love the little hearts that are on each straw- you can write your name on them to ID your drink but the heart is also for making sure you don’t “lose” your straw in your drink – keeps it from slipping or falling away from the rim, especially in a bottle. I bought this set so I could divvy them out as teacher gifts and I know that I love mine!
