How Freehand works:
Remove from you laptop or luggage, unfold the cup-holder from the down position and quickly attach the adjustable silicone straps to the side of your luggage pulls or roller-bag, insert your beverage and GO!
There is also an attachable pouch providing room to insert a phone and travel documents eliminating the hassle of needing that third hand while racing through airport security lines, terminals, jetways and your destination.
