I also have an extra set of 14 white ones (you need 12) still in there package.
I ordered 2 sets 1 white and 1 blue in case I didn't like the blue (and it was $15 shipping for up to a pound which is like over 1000 of them so I grabbed 2 sets)
PM me if you want.
There is a write up I put in the :How To" section that is very detailed on this.
