APPLICATION OF INDELIBLE INK
From the Nigerian Election Manual, 1998/99
The Poll Clerk will put the indelible ink on the left-hand thumbnail of each voter who has been issued with ballots.
The Poll Clerk should check the voter's left thumbnail for any sign of ink, which would indicate that the voter has already cast a ballot.
The Poll Clerk should wipe off any greasy substance on the voter's left thumb before applying the ink.
The indelible ink should be applied using the small stick attached to the cap of the ink bottle. (This can be done with the help of an unused matchstick if the need arises.)
The indelible ink should be applied to that place on the left thumb where the nail meets the cuticle (at the base of the nail).
For voters who do not have a left thumb, the ink may be applied on the next closest finger on the left hand.
The voter should not leave the table until the ink has dried.
