If you enjoy a bit of irony, have a gander at the Amazon.co.uk reviews (and comments) on the inexpensive Bic Crystal ballpoint pen. It seems some writers (British and non) are having a bit of fun with this trusty implement.
Some selections:
Very good if you need to write on paper.
Writes well – but it’s unmusical
A sad disappointment (it doesn’t have an inkwell)
