I backed the WRENCHit on 16th March 2016 and I chose the WRENCHit Full Set reward at US$38 and shipping to Singapore is additional US$5. In total, I paid, US$43 (S$59).
Last year I backed the Tool Pen on Kickstarter and was pretty impressed with the quality of the Tool Pen and how the project was ran.
Tool Pen is a smart & versatile multi-tool, like holding a sleek pen. It features a unique Pop-A-Point design for bits replacement.
I backed Tool Pen on Kickstarter on the 9th July 2014 and it was funded successfully on 14th August 2014 after raising US$274,794 out of their initial goal of just US$7,000. That is 40 times the goal.
