Blockey is a key management system that can simplify your pockets without spoiling the integrity of design and practicality. It is made of Aluminum 7075 which is known for its strength and scratch resistant components. Aluminum 7075 can also be found in bike shafts, rock climbing gear, aerospace applications, etc.
I backed Blockey on Kickstarter on the 12th October 2013 and it was funded successfully on 14th January 2014 after raising US$39,742 out of their initial goal of US$21,000.
