Constructed with a high-quality coil spring for excellent fatigue resistance. How to add ink: 1. Open the sliding ink tank cover located on the side of the fixed needle. 2. Keep the ink fountain level and carefully drop an appropriate amount of ink onto the sponge. How to pull out the ink thread: Pull out the fixed needle to extend the ink thread. The total ink line length is 10 meters, with an automatic winding range of 7 meters. To extend beyond 7 meters, press and hold the pre-tension release button and rotate it counterclockwise. While rotating, slowly pull out the ink line. How to rewind the ink thread: The springs automatic winding range is up to 7 meters.
