A. Wrico Lettering Pen and Lettering Guide.

1. Tubular points on this pen prevent ink from getting on the edges of the openings of

the guide. Steel needles regulate the flow of ink and prevent the points from becoming clogged with ink.

2. The under side of the guide is grooved so that ink will not be smeared when the

guide is moved from one character to another. The guide is placed directly over the portion of the paper on which the lettering is to be done.
