BEXLEY MULTI-MAX PENCIL SET is a wonderfully unique writing instrument by Bexley that was inspired by the "drop lead" pencils long-favored by artists, architects and graphic designers. The Bexley Multi-Max Pencil uses a 4.5 millimeter pencil lead which is 11 times thicker than thin lead mechanical pencils. The pencil can also convert into a ballpen (ballpen refill is included). Drop out the lead, insert the ink refill and the Multi-Max writes in ink instead of pencil. The kit includes 3 extra pencil leads, 3 colored (yellow, orange and green) leads, pencil sharpener and a ballpen refill. This was another pen/pencil from my father-in-law's collection and it has barely been used. I think one or two of the leads are slightly shorter than the others as if they were simply used to sample their writing style. This is a wonderful set and will be a great addition to your collection or to use as a daily pencil. Thanks for looking and I will ship as soon as payment has been received!
