This is from the 1980s when Filofax was a big hit. It's a 4 CLF 7/8 model. It's a Filofax that was very popular. The small, elegant "filofax" logo (photo 8) is quietly becoming a trend. Later models have a more flashy, larger "filofax" logo. Many users moved away from Filofax because of that later model's logo. The leather surface will develop a mirror-like finish over time. The plastic cover on the clasp has come off (a weakness of Filofax at the time), so I glued on one I bought at a 100-yen shop. You can replace it with one of your choice. (Photos 9 and 10) Please enjoy this rare and evolving Filofax.
