portable goods selector is disclosed herein. It is composed of two parallelogram plastic elements each provided with specifically configurated recesses formed on the left and on the right side of the plastic elements. The right-hand recess contains a series of small-sized consecutives arrows positioned in spaced-out arrangement into a column and sliding onto axles, whereas at the right-hand recess there is a self-adhesive label with a list of selectable goods inscribed thereon. The selection of goods is obtained with mere left-to-right displacement of the arrow with only one finger, in minimum time and without noting down on paper the desired goods. |
