They're okay.
The designs are very nice and they're great for some decorations. I actually bought these because recently every time I drink/eat from something made of plastic, my lips start to tingle and burn a little followed by rough patches and itchiness. I stuff a few of these in my purse and they come in handy. The reason im giving three stars is because it doesn't take too long for the straw to start to get a little soggy. In my experience, it doesn't fall apart in my drinks, but the top will start to unravel slightly. They get the job done so i'll certainly keep using them.
