The name is convoluted – but that is what they are called – “Fiches Bristol”, “Record Cards”, “Fichas Bristol”, “Karteikaten”, “Steekkaarten”, or “Schede Bristol”.
Closer to home, they might be called “index cards” – but where can one find index cards like this?
They are made of superior paper in seven sizes (mm units):
White, and in Blue, Yellow, Pink, Green, and Orange.
Five formats: plain, ruled, squared, plain with holes, and squared with holes.
They are index card nirvana. The organizational transcendence beckons.
The cards are magnitudes higher quality than those found at ‘big box’ stores – plus in squared rule ( a.k.a. graph paper) format. They are absolutely unlike the brands many of us have had to resolve ourselves to using.
The cards are thick coated white paper (210g/m2) with purple ruling. The boxes they come in open like playing card boxes. (To me, the smaller cards seem thinner than the larger cards, but there is no documentation of this.)
With pencils, they are a great pair. With fountain pens, there is no feathering, no bleed through – but drying time may be more than some prefer. This is serious writing paper, in another format.
Overall, they are one of the best stationery items I have ever found. The creative and organizational power they offer is immense.
