The jury box of a county shall contain the same number of capsules or containers as there are names on the jury list prepared by the jury commissioners from the latest official list furnished to the county by the State Election Commission each year and provided to the clerk of court of each county not later than December first of the calendar year. The capsules or containers must be small, opaque, and as similar in size, shape, and color as possible at the time of original purchase or the repurchase of additional capsules. By a slip of paper placed therein, each capsule or container must be numbered, beginning with number "one" and continuing consecutively through the number of qualified electors on the jury list prepared by the jury commissioners as hereinbefore provided. All these papers must be of similar kind, color, and weight so as to resemble each other as much as possible without distinguishing marks. The capsules or containers so prepared must be placed in the jury box constructed as required by law.
