These invitations are sent by exhibitors to their clients. Each exhibitor receives a package of invitations to the exhibition, as well as a package of invitations to Industry Day (Thursday) for their special clients, so that in a slightly looser atmosphere they can meet the most important of them. Along with invitations we send identifiers to the staff who will service the stands of the companies participating in the exhibition. We sensitize exhibitors to carefully check shipments and take identifiers with them to the exhibition.
