What Tension Customers are Saying

The team at Tension treats us as though we are their number one client. They treat us like they are a small mom and pop shop, but actually they are a large long-standing national company, and we get that backing. You don’t get that kind of customer service from other large envelope manufacturers.

Valerie Jones , Director of Production Kersten Direct

I was having problems finding a dependable supplier for blank 8.5x11 forms with a single perforation. When my sales rep at Tension learned about this issue he developed a solution, getting the paper I needed and stocking it at the warehouse. Now instead of waiting a week to get stock in, I can have the forms I need delivered the next day from Tension.
