The beginnings of the Merkur brand date back to 1920, when Mr. Jaroslav Vancl founded the Inventor company in the town Police nad Metují, Czechoslovakia. The first original metal building kit was patented under the name Inventor. Originally, the metal parts of this kit were connected to each other with metal hooks. In 1925, the manufacturer came up with a new system, which has remained unchanged to this day. The metal parts of the kit have since been connected with screws and nuts. With this step, the kit came very close to real constructing and thus enabled greater opportunities for play and creative work of children. With the transition to the new system, a new trademark was registered for the kit - Merkur.
At the turn of the 1930s and 1940s, a number of kits grew. The boom of MERKUR kits began. Surge of development continued until the beginning of World War II. After the Second World War, the factory was nationalized. After the fall of communism in Czechoslovakia, MERKUR was practically doomed however things took a positive turn recently when Merkur gained a new owner and comes to life again.
