PW100 Passive Pen only Suitable for Drawing Tablet H640P H950P H1060P H610Pro V2 HS610 HS64

It's the the original brand and does not have replaceable tips, but it works great.

The description clearly says that the pen is compatible with the GC610, which I found odd, since I thought the pen I lost was active, but my GC610 won't recognize the PW100 pen at all, regardless of driver updates/reinstalling software. No matter what I try, the pen just isn't being picked up by my tablet.

Bought it thinking that it was original, now I see that it is a knock-off. It works well though. Feels cheap by the touch. But the worst is that it doesn't came with replacement nibs, the nibs cost extra $7, so it would be better to pay $22 on the original one!
