Twsbi Ink Bottle Sapphire Blue - 70 ML

WSBI has revealed itself to be no less adept at crafting inks. Featuring vibrant, well-behaved colors and beautiful, cleverly designed bottles, TWSBI inks make a wonderful addition to any fountain pen user's collection. This ink comes in a frosted 70 ml glass bottle and includes a plastic reservoir that makes it easy to fill your pen even when the bottle is almost empty. Simply flip the bottle upside-down and back to fill the reservoir, and you're ready to refill your pen. The top of the TWSBI Diamond 50 Inkwell is also interchangeable with the top of these 70ml ink bottles, for another easy way to fill compatible pens. With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.
