Swing Cell Compact, model 6-78041-00, is a braille training device designed for use by individuals who are blind or have low vision. It consists of two rectangular blocks, each with three holes into which pegs can be inserted to represent braille dots. This device helps students understand the relationship between the braille cell and the keys on a braille writer. It is similar to the Swing Cell (see separate entry), but smaller and lighter and without the base. COLOR: Yellow blocks with black pegs.
