A device for forming Braille characters for tactile sensation or impression onto an embossable substrate includes a substantially block-like main body. At least one array of six Braille printing pins is contained in the block in a 2x3 Braille cell configuration. Each said pin is contained in a first cylindrical bore and is movable between a retracted position whereby it does not protrude from the block, and an extended position whereby the tip of the pin protrudes from the block. Means are associated with each said pin for maintaining each pin in an extended position.
