The Hot Tipz Kistka #000 3X Fine is a traditional kistka (wax pen) designed to use a candle as a heat source. The kistka is made with a precision tip, the same that is used in Electric Kistka -- which ensures perfectly consistent lines. The line dimension of the #000 3X fine is .010. The design of the pen is unique, with a large brass end that captures and holds heat for an extended period of time. This allows more writing between warm-ups in a candle ... and has led to the pen's customer created nickname as almost electric. The #000 3X Fine Hot Tipz Kistka comes with a charger pin, which helps ensure consistent wax flow when writing. Made in the USA.
