My urban sketching bag, a Trespass Mini Belt Bag, just right for an A6 landscape Seawhite travel journal, a small box of Winsor & Newton watercolours and Pentel Aquash water brush, a Pentel brush pen and Lamy fountain pens filled with black De Atramentis ink, except the yellow Lamy Safari which has a regular Lamy ink cartridge.
Sadly the pen that didn’t make it into the final selection was my Lamy Vista with an extra fine nib. After several refills and flushings out the ink still isn’t flowing into the nib.
