The multifunction Troika Construction ballpen really can do a lot! Finished in yellow with silver accompaniments, this all-metal Construction pen is a stylish writing instrument, planning aid and tool box all in one. Features include: four different metric ruler scales (1:20, 1:25, 1:50, 1:100), mini slotted and Phillips head screwdrivers, a spirit level and a capacitive stylus top. Simply twist the knurled metal grip to begin writing or to retract the black ink refill. The solid metal barrel gives this ballpen a nice weighted feel and its hexagonal shape means it won't roll away when you put it down. Supplied in a sleek Troika presentation box.
