This is not a vey big topic where would like to introduce a simple way to boost up fading out colors of ink inside your pen. Or maybe you just found your old pen under the couch and your first intention is to throw it away. Sure, you should have some little ink still inside that you could push from the pen, this article is all about.

The list of material:

1)Syringe

2)STL printed adapter TPU (syringe to Ink)

3)BIC pen

4)3D printer (aound 10 minutes to print adapter TPU material)

1-Plug the adapter TPU (small diameter to ink)

2-Plug the syringe to adapter TPU (big diameter)

3-Pressurize the ink and keep writing on junk of paper (until you get the best results)

(Do not reverse the processus: don't create vacuum inside the ink)
