I Trust the good Dr is refering to the Late Oscar Wilde?
"Sanity is a playground for the sluggish mind"
"Consistency: The last refuge of the unimaginative mind."
The Pen I prefer is the Papermate Flexgrip, it works well even on damp paper.
Have tried other pens including Gell ,but nothing has been found yet to rival the Flexgrip.
The trouble with stamps is that they lack that personal touch,so robotic.
Diveing to Periscope depth...
