# Continuing with Special Equipment Calligraphy Items:

The Pentel Hyperaser.

This is like 'do mistake erasure with ease'. When an error has been made with ink or gouache on your work, just use the Pentel brand 'Hyperaser'. Anyone who has done serious commission style work needs tools with a professional edge, this is one of THEM. A retractable eraser made with what appears to be fiberglass and other high erasure content. An unusual effect is that while the ink/paint comes off, the paper/card surface almost totally remains unaffected, (best results on hot pressed papers, cards, vellum skin). Buy one to see for yourself.
Retail price $12.50 each, ON SALE 25% OFF AT $9.35.

KERN PRONTOGRAPH WRITING TEMPLATES.

Sample pictures show the ITALIC style lettering of the 0.35, 0.50 size templates.
Kern Prontograph writing templates are available in 2x sizes. You can use them with these sizes of technical pen;
0.35 tip, 0.50 tip. The style of lettering is slightly leaning, that is, in an ITALIC style.
Actually any brand of technical pen held vertically in these templates will allow writing of the templates lettering. This includes Kern, Reform, Rotring, Staedtler, Erograph etc.
Each template has the CAPITALs, lower case letters, plus most other symbols - like [ ], ( ), ?, +, -, /, * and arrows etc. Another feature of successful neat writing with one of these templates with a tech' pen, is the raised template. It slides above your paper/card on 2 (top & bottom) aluminium rails, this stops wet ink from touching the template as you write. It can also be turned upside down to get reverse characters, with the same effect.
