I've just unearthed an unopened pack of a dozen of these pens, probably
more than 15 years old and they don't work.
I've dipped the tips in boiling water and then meths but they only write
for a short while, which suggests the ink has got too solid in the tubes.
Any other ideas for freeing them before I bin the lot? White spirit added
to the tubes perhaps?
