Hip Flask

DESIGNER: Felix Ure MATERIAL: Solid Brass SIZE: 2.83" (72mm) Hip-Flask is Felix Ure's widely anticipated second design, following his very successful Titan take-apart puzzle. Described as a fiendishly challenging, multi-stage, sequential discovery puzzle, the goal is to remove the lid from the flask. Machined from solid brass, Hip-Flask measures 72mm in height and weighs 750g or approximately 1.5 lbs. The brass is left unfinished, leaving it to slowly patinate and darken with use.
