Many think that these are boba tea straws, but they are great for pretty much everything. I got these for my little girl. She LOVES silicone straws, and I love them because they don't hurt her mouth. We have used metal, plastic and other types of straws, and inevitably she somehow ends up with bumps or cuts from the straws. These silicone straws are wonderful for littles that like to drink everything with a straw. They are made of a soft silicone, that will stand as a straw but will bend when necessary. There is no sharp edges on the straws, which I LOVE, because they won't hurt my kids. These have become a staple in my family already, and I will be buying more.
