Our glass drinking straws by OPTITHERM are 100% Made in Borchen / Germany! We are now the third generation to run our glass construction company OPTITHERM Sander, we are a real family business and experts in all things glass! Thanks to the regional cooperation with our partners, our glass drinking straws are not only particularly sustainable, but also inexpensive for our customers! Because let's be honest: we're talking about glass drinking straws and not a luxury product. Everyone should be able to afford sustainability!
