Absolutely amazing. We needed a large quantity of the dichroic film in a pinch and MPC supply made it happen for us!!! They truly saved the day. Michael, who helped us with our purchase, was so extremely helpful, prompt, friendly, and professional. It is hard to find great customer service in today’s world, but I assure you you will find it here. I am also so impressed with the quality and value of the product. We got many different samples from various companies and MPC supply had the best quality for the lowest price. We used the film for an art installation and it turned out great. We are now life-long customers of MPC!!!
