I never realised before that these two binders are identical in layout and design. Unusually for a Filofax of this era and design, the Tejus is named not after a city (as the Dundee is) but a type of lizard.
If you look at the photographs below, the Dundee is the crocodile print and the Tejus is the lizard print.
These binders are stiff and light and wear very well. I am not sure if they have stiffening in the cover as the covers are flexible and thin. The colours do not show up well here but they are vibrant yet subtle (if that makes any sense at all!)
Both of these came from Bouteia on eBay.
