LAMY T52 bottled fountain pen ink comes in a solid glass bottle with an ink-residue-collecting basin and an inbuilt roll of blotting paper to make refilling clean and easy. There's 50ml of ink, which goes a long way, making this product great value for money. Colours available include professional blues and blacks, and more playful red and turquoise. This ink will suit any brand of fountain pen that uses a conventional piston filling or ink-converter set up. You can use your LAMY fountain pen with a Z28/Z26 LAMY converter.
