We provide Stem a Stem/Mark with complex processing of deliveries directed to questioners of market research. Stem/Mark provides services in the field of marketing research in the most varied fields like media, pharmacy, tourism, banking, public administration, internet, etc. The implementation of these contracts places a high demand on the assembly and pairing because these are documents intended to be delivered to the hands of specific persons. We have been working together with Stem and Stem/Mark since the beginning of our activities, and they regularly make use of the possibility to organise social events at the Vrtba Garden.
