Let customers speak for us
from 109 reviewsNice to grip, very smooth, bright coloured ink.

Fountain pens are superb !!! The ink doesn’t dry on nib while not in use.

The Pure Beautiful East Gel Ink Pens (Set of 5) are smooth, comfortable, and great for everyday writing. The ink flows well without skipping, and the grip feels nice in hand. Perfect for notes, journaling, or doodling. A good choice if you want reliable and stylish pens!

Value for money product. Used fountain pen after ages and extremely happy with the experience. Good Pen!! Happy writing 😊

The Pens are excellent value for money -
Well made and have a premium look.
I’d switched to 0.5 mm from my usual 0.7 mm & they write as expected.
I’d recommend these pens.

Awesome. Hopefully the refills are easily available too.

Me and my friends played with and also won in pen fight. And very smooth and soft and nice colour and texture
