It is impossible for a manufacturer or a seller to carry all samples of their products, to customers on every visit. It is now a trend to have a really high-class brochure, catalog, a pamphlet, to display to the customer of the varied range of models, machinery, and products dealt in.
A brochure tells stories of the companies history, experience, products, with neatly aligned content, tables, and applications of their goods, and most importantly educated the customer, in brief, all relevant details, and comparisons to other models available.
It is of utmost importance to have high-resolution pictures as the display so that the customer feels comfortable ordering your product over others. It is a general practice to you pictures of the internet, but how humiliating would it be if the customer should look up for similar products and come across the same picture as displayed but with some other companies branding!
