Hi there,

I just discovered through this subreddit that using the fine liner extends the tips’ life, but no info on how long exactly ?

I just got my rM 2 and I like it a lot, I think I am going to use it like 6+ hours everyday, mainly for math problem solving. I ordered it from the U.S. since it’s not available in my country, so it’s not easy for me to get replacement items.
