What Printing Supplies and Resources Do We Use With The Investment Dominator?

So what types of printing supplies do we use with the Investment Dominator to print off our mailings?

• To print our letters and contracts we use standard A4 paper like this: https://goo.gl/aDiuEJ
  

• For the envelopes, we use a standard #10 envelope like this: https://goo.gl/jzrPIj
  
  (Linen envelopes like this also work quite nice and may get you a slight bump in open rates: https://goo.gl/BMoukj )
  

• When we send out our offer, or option agreements we print them on standard A4 paper and put them in an oversize 9×12 envelope like this: https://goo.gl/rMVIXX
• and print the address on a large 2×4 label like this: https://goo.gl/O67d1c
  
  (NOTE: we also use these labels on our property file folders https://goo.gl/xe0RdU to organize our files offline.)
