In No. 12 “M-K” for 1984 described how to lengthen short pencil cut with a thin-walled tube. I’m here for several years are not a pipe extender, and a cap from a ballpoint pen.

If the cap will be too big. the pencil should be screwed a strip of paper — it compensates for the gap. K. BARSAMIAN, Yerevan
