Simply remove the red cap, pull the plug out with the straw attached, pour in your favorite cold or frozen beverage, replace the plug and cap and drink from the bite valve on the end of the straw!
NO! That's the point! Once the plug is installed, nothing can get in or out or your beverage. The Sip-N-Oodle can even go under water while you float on it and nothing can get in.
No need to worry. Due to the way they are produced, sometimes the bite valve slit is perforated and not separated. Simply use your fingers to grab the bite valve on each end and pull apart. The bite valve should open up relatively easily to reveal a slit. If that doesn't work, reach out to us on the contact page and we will be happy to assist!
