210a to be used as an antibiotic white axle 210 are contained in an antibiotic solution in which distilled water of 25 to 35 weight%,
hydrogenous colors of 17 to 23 weight % , an inorganic antibiotic agent of 25 to 35 weight % and a binder of 17 to 23 weight % are combined and is dipped into water whose temperature is approximately 10 to
20 °C for approximately 48 hours. Thereafter, the wood axle plates 210a are taken out from the antibiotic solution and is then boiled at a temperature ranging from about 60 to 70 °C for about 120 hours. Next, the wood axle plates 210a
are dried naturally, thus completing a wood axle plates 210a for an antibiotic white axle 210 as shown in FIG. 2(A). After the first step is performed, a fragrance injection process in which a completed nontoxic antibiotic pencil 20 is processed to emit a sweet fragrance can be selectively performed. In the fragrance injection process, the wood axle plates 210a on
which the antibiotic process is carried out are dipped into a frankincense solution in which distilled water of 55 to 65 weight%, a binder of 12 to 18 weight%, a natural hydrogenous aromatic agent of 22 to 28 weight %, oily perfume of 3 to 8 weight % and an ant i foaming agent of 3 to 8 weight % are combined for approximately 3 to 6 hours
and is then dried. Thus, a sweet fragrance can emit from the completed antibiotic pencil 20. If a hot wind is employed in this dry process, it is preferred that the hot wind is performed from the bottom to the top of the wood axle plates 210a so that a leveling phenomenon is not generated. If
the dry is good, a natural fragrance can be obtained. Further, a fragrance used in this process may be aromatic perfume, rosemary perfume or the like. Referring to FIG. 2(B), long grooves into which the pencil heartwood 220 will be inserted are formed in the two wood axle plates 210a by a predetermined width so that they are spaced apart as much as the diameter of the antibiotic pencil 20. The pencil heartwood 220 is located on the grooves. The two axle plates 210a are disposed to face each other and are then compressed together. In this state, the two axle plates 210a are cut in order to obtain a desired shape.
Thereafter, referring to FIG. 2(C), the surface of an individual
pencil trimmed thus is processed and a white axle terminal 230 is then formed at one side of the pencil. The nontoxic antibiotic pencil 20 is
