I'm planning to get this one off of Amazon

https://www.amazon.com/gp/product/B0B2QBRGD7/ref=ox_sc_act_title_1?smid=A30FF1YSS5LSJQ&psc=1

until i found out it's not by Huion despite looking perfectly similar to it, I thought it comes with nibs though, atleast one

It says it takes PN02 nibs, but would the PN03 spare nibs I have already work on it? They seem to have a similar design peg save the length of the tip, apart from color

Reduced to my base instincts, I have started carving new replacement tips out of wood. Surprisingly effective, if a bit difficult to find wood that will hold up at that size. Still keeping an eye out for other alternatives.

​

EDIT: I picked up a Yoidesu Stylus PEN68D Drawing Tablet Pen, which (while battery powered) is compatible with both the PN01 and PN04 Huion Nib Replacements.
I had to play around with the sensitivity settings to feel familiar, and I'm not sure how durable it is long-term, but for ~$20 it's a good deal and they still make nibs for this one.
You can find the pen here: https://www.amazon.com/dp/B0B2QBRGD7?psc=1&ref=ppx_yo2ov_dt_b_product_details
