Pilot FriXion Synergy Knock Erasable Gel Pen - 0.3mm 0.4mm 0.5mm Limited Edition

Pilot FriXion Synergy Knock. The Synergy Knock line of Pilot FriXion ballpoint pens introduces an innovative "Synergy tip" that combines two types of metal tips typically available for ballpoint pens - the "cone" tip, which is sturdy and provides a stable writing experience, and the "pipe" or needle point tip, which allows for precision. The new proprietary "Synergy" tip from FriXion combines the two conventional tips to create a high strength writing tip with a smooth ink flow, even for very fine writing. 

The FriXion Synergy Knock pen has a matte gray barrel that is smooth and comfortable to grip, with a pen clip that matches the color of the ink. The FriXion eraser on the end of the pen body comes in a different color for 0.5, 0.4, and 0.3 mm diameters, making it easy to distinguish the point size of your pens in your pencil case. 

Since the ink reacts directly to temperature, it is recommended not to leave it under direct sunlight or in environments hotter than 140 Fahrenheit.

About FriXion:

The FriXion ink is erasable by rubbing with the tip of the pen to create the frictional heat needed for the ink to disappear. Since the ink reacts directly to temperature, it is recommended not to leave it under direct sunlight or anything that's hotter than 140 Fahrenheit.

These pens pair the same beloved thermosensitive ink found in other FriXion pens with a sleek, retractable pen body. Just push the clip to extend and retract the tip. The special rubber eraser at the top of each pen allows you to erase conveniently without pressing the retraction mechanism. The pens write smoothly and erase without a trace!The FriXion Point Knock also features Pilot's unique Synergy tip, which combines the precision of a needle point with the durability of a conical point.

FriXion pens use a special thermosensitive ink that turns invisible when rubbed with the built-in friction "eraser." The ink disappears cleanly without using up the eraser or creating any dust or smearing. The ink will also disappear if exposed to other sources of heat or friction, so we advise against using these pens to address envelopes or leaving anything written with them in a hot car. Like magic ink, erased FriXion ink reappears if placed in a freezer or otherwise exposed to temperatures below 14° F (-10° C).
