The ingenious design of the Ohto Tasche allows one to carry it as a small compact pen when closed, but use it as a full sized pen when open. The slim pen measures approximately 4 inches when closed and 5.77 inches when in use with the cap posted. The pen line is available as a fountain pen, ceramic roller ball pen, needle-point pen, and mechanical pencil.
Pen dimensions: 102.1 mm (4.02 inches) closed, 146.6 mm (5.77 inches) with cap posted x 9.8 mm (0.4 inch) diameter. Weighs 14.5 g.
