I think it is a such a pity that Filofax has discontinued these – they are gorgeous and real farmed exotic rather than embossed as 99% of the exotic binders out there. They also wear extremely well and are tough as iron, but light.
I have a Buttercup ostrich and lizards in red and green. For comparison in the one photograph is my green Tejus which is lizard embossed, but a good quality binder if a real exotic is beyond your reach. It is also vintage so the rings and the leather were really made to last a lifetime.
