Aristo Γεωδαιτικό τρίγωνο 22,5cm με πιάστρα (1650/1)

The TZ triangle 1650/1 (without facet) has a hypotenuse of 22.5 cm. The ink knobs form a distance between the TZ triangle and the surface to prevent the lines from blurring and to protect the division. ARISTO TZ triangles are made of crystal-clear Plexiglas® in Austria.
