One of my passions is Calligraphy. The legendary cameraman Subrata Mitra sent me two calligraphy pens he got hand made for me at the Calcutta Book Fair. They have a dual nib and are handcrafted. We were both obsessed about broad nibs. the broader the better!
They are fairly basic, don’t have a cartridge, you either fill the back with ink and pray that it doesn’t spill or dip the nibs in a bowl of ink.
They write beautifully and are inexpensive. Or at-least when Subrata-da got them made for me.
Well now they are priceless.
