Nowadays, straws become necessary for drinking beverages. However, the disposable plastic straws increase some environmental problems. In order to increase reuse of straws and still keep sanitation, an innovative and portable straw tip is designed. It could be carried by the users and be stuck on a general straw. Since the users drink beverages with personal tips, some diseases from lip touches could be avoided. When they finish drinking, users could take apart their tips and return general straws to the beverage stores for reuse.
