Mobitec was a French brand of the toy maker Montblanc. Montblanc started selling a LEGO clone under its own name in the 1960s. Later it was sold under its own brand MOBITEC. Montblanc/MOBITEC is a clone of the 1956 LEGO, the last pre-"Patent Pending" brick issues, with the studs hollowed from the bottom. But the studs have a smaller diameter and so they do not connect with LEGO. However, the system is quite likeable and the colours chosen with a French measure of good taste.

Below a comparison of Mobitec material with a LEGO brick (Figure 1) and the cover of a #7 roll-package (Figure 2).
