As "brochures" here are meant mainly informational prints about products or/and services. They are the "trump card" in the field of corporate identity and intent to be your best "face".
A well-designed brochure with appropriate content is potentially the perfect business promotional tool. It is the printed matter that classifies all the information and displays all the advantages of your products or services in the most comprehensible way and with the best results.
Brochures as opposed to leaflets, have to be "high-priced" in relation, of course, to the objective value of the content. Usually, however, are given facing the person concerned, so you don't need large quantities of printed matter. The recipe here is "less is more"!
