Cruising around your bike just became a little more fun with the creation of this 6 pack holder. Handmade in Portland, Oregon by a company called WalnutStudiolo this little invention was originally intended as a Polo Mallet Holder for bikes. What the hell is a Polo Mallet Holder? How many Polo Mallet Holders did they intend on selling? 5? Whatever. Someone had the right mind to put this thing to good use. I love when being green and alcohol can be at harmony with each other.
