Sio Montage
"Sio Montage is born in the years '56 - '57. The first start was a thick plastic bolt van Blokland got hold of. This made him play with all kinds of opportunities that were offered by the bolt. After the bolt came a nut, perforated wooden strips, blocks with threaded shafts, discs and wheels. " (Het Parool, Dec 1, 1962).
The Sio Montage system is based on a size of 2.5 cm. All parts can be found in this grid.
The slats and blocks are coloured in bright transparant colours using the Sioliet dyeing method.
The Sio Montage collection has been expanded throughout the years with many new parts and construction sets. These created new possibilities and challenges to the young builder.
Sio Montage building sets were produced by Sio in very large numbers and exported to many countries.
