Thank you very much for your comment. We will gladly forward this internally to the responsible department and hope that this will be checked promptly.

Bought the straws, package measurement is correct (20.5cm) the straws are 20.0cm, and not 20.7cm as written in description. Sent a message to customer service, hopefully they will change it. Now we can all rest assured that this mega important issue is cleared up! :D
