A Braille writing instrument has a housing which has a first end and a second end, extending in a first direction. Six plungers are positioned near the first end, arranged in a first column of three plungers and a second column of three plungers. The first and second columns are adjacent to one another to define three rows of plungers with each row having two plungers. Each plunger is movable in the first direction between a stored position and a write position. The instrument further has six styluses which are positioned near the second end, and are arranged in a first column of three styluses and a second column of three styluses. The first and second columns of styluses are adjacent to one another to define three rows of styluses with each row having two styluses. Each stylus is movable in the first direction between a retracted position and an extended position. Styluses in the first column are substantially collinear with the plungers in the first column, and styluses in the second column are substantially collinear with the plungers on the second column. The instrument has means for connecting each plunger in the first column to a stylus in the second column in the same row, and each plunger in the second column to a stylus in the first column in the same row. Each movement of a plunger from the stored position to the write position causes its connected stylus to move from the retracted position to the extended position.
