Recently purchased a Conway Stewart rollerball pen for the first time, after reading a piece on them in Country Life. I’ve used Mont Blancs and Pelikans in the past, and enjoy this more than either. The action is so smooth and, while it’s a weighty pen, it’s so well balanced and surprisingly agile for its size. The smallest quibble is the angle the rollerball needs isn’t terrific for writing in bed - but gives me the perfect excuse to purchase a lap desk! I suspect this pen will last me forever, but would not be surprised if I buy another in the future.
