TWSBI Ink 70ml

TWSBI Ink 70ml For Fountain Pens

TWSBI Ink 70ml is another new venture from TWSBI.

Supplied in an attractive frosted glass 70ml bottle, it is available in four colours: Blue, Black, Red, Midnight Blue and Blue Black.

The Blue Black is particularly interesting due to it being the only waterproof colour from the other four, as it uses iron gall ink. This traditional ink mixes iron and tannin to give a deep dark blue that forms a permanent mark on paper when dry.

Bottle cap is made to also fit TWSBI’s Diamond 50 bottle cap, insuring a mess free fill without the inky fingers.
