The most professional store for pens, paper, etc. They will be opening in Panska pasaz soon. The owner is a true master. You can find all inks, pens, wallets, you name it. All Moleskines, Paperblancs, NASA notebooks, Luchtenfort, faber Castell, mont blanc, visconti and many others. They make initials on pens, can engrave everything and are always attentive and hlepful. Plus they have pen service so whatever is happening with your ink or other pen, you can have it fixed here. One of my face places in Prague! :)€
