Dry Ice

“The quality of the product, packaging with poly bag, card board on top and shrink wrap was what we expect and speaks well for why we want to do business with you folk.

-John F., J Frazier Service Company

Dry Ice

“You told me you would be able to cut my consumption down and for now you have. Your ice is working better than what I used to get and I am sure it is because it is so fresh it works so much better. Also , your driver thanked me again for the business, he is just a very friendly person. I wish more drivers who came here were like him.”
