To answer your first question, yes, these reusable straws are made up entirely of bamboo stalks. And to answer your second question, yes, they work literal wonders for slurping down morning smoothies, sipping Saturday night mai tais, [insert other fancy drink here], with none of the guilt associated with using landfill-bound plastic. Even better news? They come with a convenient pipe cleaner and a cinchable pouch (a goop.com exclusive!) for neat storage. Pro tip: Keep one at your desk, one in your center console,  even tucked away in your work tote.

• Set includes 4 bamboo straws and wire cleaning brush
