Lenovo active pen 1 nibs?

hi guys! I bought a month ago a lenovo active pen on ebay,because it was a bargin..but what i didn't notice was that it didn't come with the nibs or extractor ring.
When i first used the pen it was okay and acceptable but then but this week the pen curosr was inaccurate. And its because of the nib btw not the laptop. So i tried looking online for nibs because i can't afford a wacom ink or active pen 2 rn.
Also i need an extractor ring and i can't find those online either.
I heard a rumor that Wacom ink nibs work with Lenovo active pen 1 ,can anyone confirm that? So i can forcefully take the nib out even if it gets damaged i have the wacom nibs
