Is the grocery bag holder clip the greatest invention of all time? Most likely. Will I ever use it? Most likely not. How can I prove my machoism and carry in 15 bags in one trip, when I am just using this grocery bag clip meant for grannies, weaklings, and puny nerdlings. At the end of carrying in all those bags I need to have imprints on my hands that will last for at least an hour. Nonetheless, the grocery bag holder clip has a self locking handle, is made of plastic, and can carry up to 50lbs of bags.
