After receiving free sample from design team of Emenac Packaging, I still had doubts with the final box design so I discussed with the manager to pay in installments. He agreed with me and I paid only 70% at the time of order. After the production, the quality assurance team sent me images of the boxes which I approved before paying the rest of the 30% amount. This favor given by the manager was really impressive that made me the permanent customer of this company. Always felt special working with them.
