The telescopic writing instrument has adjustable length for comfortable writing when extended and ease of transport when contracted. It consists of a pen or pencil cartridge fixed inside the inner substrate of three concentric substrates that slide within each other.In its extended length, the instrument is standard length with the fingers holding one end of the instrument, and the other end leaning comfortably against the base of the hand. In its contracted configuration, the instrument is about half-length with the outer substrate extended over the pen or pencil cartridge to prevent unintended markings.The instrument is simple and easy to use, reconfiguring in about one second.
