OPTIMA PENS

The Optima 'Heavy Duty Style' pens (Standard Skew shown) are pre-sharpened and polished, ready to go right out of the package. Blade or flattened HD tips are about 0.014 to 0.015 inch thick. The body is made out of extremely durable composite materials that retard heat conduction, and have a soft foam cushion grip. The foam pen grips are soft and comfortable, (no more sore fingers). 
Shorter length tips allow you to get closer to your work and have more control than other brands. 
We recommend that you also get the new Heavy Duty Super-Flex cord for this pen, as it will give you rock steady tip temperatures.
