In their smuggling operations, the Smoloskyp couriers used various ways to obtain and to transport samizdat and other materials of the Ukrainian cultural opposition from Soviet Ukraine. Manuscripts were usually copied as microfilms, hidden in luggages or parcels (in souvenir dolls, busts of Lenin or Shevchenko, etc.). In order to smuggle materials, Smoloskyp agents sometimes used official Canadian Communist delegations that visited Ukraine, as their luggage was checked less thoroughly on the border. Unbeknown to them, Smoloskyp agents attached microfilms to their luggage or talked them into carrying some souvenirs (with microfilms hidden inside).

Nowadays, two doll-containers are displayed on the Smoloskyp permanent exhibition in Kyiv as a symbol of the creative agency of both Ukrainian cultural opposition and Ukrainian diaspora in building hidden communication channels and making the case of the Ukrainian oppositional movement internationally known.
