Blockey
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.
The estimated delivery date is in May 2014 but it got ship on 12th June 2014 and I got it on the 27th June 2014. They delay is only a month which is pretty good for a Kickstarter project.
I am one of the early birds, so I paid US$27 + US$7 (Shipping) and that amounts to US$34 (S$43). I chose the extended version “5 key set” in silver.
