In fact, the straw is the REAL piece of plastic KD sucked from during a SONIC fast food commercial the NBA star shot back in March, when he was promoting the Kevin Durant Signature Slush.
The straw also comes with a certificate of authenticity personally signed by KD that reads, "This is the actual straw from the Candy Slush that Kevin Durant (KD) had on the set of a SONIC commercial shot on March 26, 2015."
There's more ... Sonic is also auctioning off the ACTUAL candy from KD's slush ... which also come with a C.O.A.
Don't worry, it's not some cheap stunt to make a few extra bucks -- the auction benefits the Limeades for Learning program ... which raises money for educational programs across the country.
So far, bidding on the straw is already up to $40 ... but there's still 5 days left to go!
