The lead in the Grip Matic mechanical pencil is advanced automatically, no button-pressing necessary. The comfortable rubber grip zone makes writing a pleasure. Choose between two line thicknesses: the 0.7mm lead for particularly break-resistant writing or the 0.5mm lead for fine writing. The lead can of course be fully retracted so it can be carried in pockets.Details:Brown barrelFits 0.7 mm and 0.5 mm lead12 pencilsEach package includes 1 tube of 0.7 mm leadIntegrated eraserAutomatic lead feedRubber grip
