A multifunctional pen includes a penholder and a refill provided in the penholder. A clip is provided on the penholder. The penholder comprises an upper penholder and a lower penholder hinged to each other. The lower penholder may bend and tilt toward the upper penholder through a hinged joint. The clip is arranged on the upper penholder and across the upper penholder and the lower penholder. A tail end of the clip is raised and a pressing raised strips for a mobile phone is provided thereon.

A marking instrument having a plurality of removable writing nibs serially aligned so that an operator can remove a spent or fluid-affected writing nib and, thereby, access a fresh writing tip.

A ballpoint pen is disclosed. In the ballpoint pen, an oil-based ballpoint pen ink composition has an ink viscosity with a range of 500 mPa.Math.s to 15000 mPa.Math.s inclusive at 20° C. and a shear rate of 500 sec.sup.-1. A ball has a ball diameter of 0.5 mm or less. A tip distal end portion includes a first swaged portion and a second swaged portion. The first swaged portion has an inclination angle with a range of 90 degrees to 100 degrees inclusive. The second swaged portion is provided closer to a distal end side of a ballpoint pen tip than the first swaged portion and has an inclination angle with a range of 110 degrees to 130 degrees inclusive. An angle of a bottom wall of a ball holding chamber is the same as the inclination angle of the second swaged portion.

A sublimation device with an actuator body to enable modulated vapor production and including a heating bowl and a heating tip with complementary shapes.
