Refill for 0.7mm (medium) Paper Mate Inkjoy Pen brand. This is a gel refill that dries 3x faster than any normal gel pen with no smudges.
 
♥ When your ink runs out, unscrew the pen tip and replace the ink pen cartridge keeping the spring and replace with new gel pen refill. ♥
♥ Important! Keep the springs from your other pens. You will need that for the refills to work properly. We are not responsible for lost or damaged springs and we do not offer them.
