Description
A blue barrel, medium tip, mini BIC 4-colour ball point pen. The BIC 4-colour biro was originally invented in 1969 and first released in France in 1970. Writing in black, blue, red and green, the ink colour is selected by depressing the corresponsingly coloured plunger at the end of the pen. Small lugs on these trigger mechanisms serve to displace the current ink tube (which returns to resting position) whilst pushing down the new cartridge (via an internal spring) and locking it into place. The range has since expanded to include almost thirty different variations, including this miniature version of the original blue barrelled pen. See AIBDC : 008558.1-4 and AIBDC : 008604.1-3.
