One for the carto tank users
...its discountvapers
Here is a great deal on a carto punch. Those looking for any sort of deal on carto punches had to deal with saddle valves. Finally one that is small and works well. I use one similar to these and it never fails me.
WHERE: http://www.discountvapers.com/
THE DEAL:
1 Carto punch for 5.99
