Object of desire

The Pentel brush pen comes with ink cartridges - it's "a truly portable brush pen". I hadn't realised, until seeing and trying the one owned by my friend, that I needed a truly portable brush pen, and needed it immediately - well, tomorrow at the latest!

This review points out that it needs to be used slowly, and it isn't suited for English calligraphy, but rather for flowing  non-western scripts. Its price, on the manufacturer's website, is £13.65, with refills costing £5.76 for a pack of four.
