1. Frixion ink is a thermosensitive ink that will react to temperature. The writing reacts with high temperature (greater than 60°C) to turn clear or invisible. Writing that turned clear/invisible will react with low temperature (lower than 0°C) to allow the color to reappear again (this process will take around 30 minutes).
2. Synergy Tip. This new tip is a combination of "Conical Tip" and "Needle Tip". Synergy tip allows precise writing with smooth and consistent ink flow.
3. Metal Mouthpiece increases the weight and lowers the center of gravity. This will provide a more comfortable writing experience.
