Harold Muniz Ortiz
Pacdora has saved me so much time as a designer. I've been able to focus on designing, rather than dealing with dielines. The best feature is the easy customization of the templates to fit your packaging needs and the 3D renders that clearly show what the product will look like.
AM
I'm a graphic design student and find Pacdora extremely helpful when mocking up projects. The convenience of Pacdora allows me to spend more time on designing rather than figuring out all the technical nuances in building dielines. Highly recommend Pacdora.
