Stirring rods are a basic laboratory tool used for stirring and mixing chemical solutions of various types.Glass stirring rods are made from solid glass rods of varying thicknesses.  Specified thickness is an approximation and can vary by as much as 1mm.  Traditionally, stir rods were made of any spare glass tubing or rod laying around the lab and were not uniform.  Also, these are hand-made and hand fire polished so all the ends might not look the same.  These rods are primarily intended for laboratory use.
