Question about the apple pencil tip

The original box that the pencil comes in should come with an extra nib, but these things are troopers regardless. The longlivety of them mostly depends on the amount of use; I'm an artist and use it quite a bit, but I've been on the same nib for about a year and a half, no worries. If you happen to need more nibs, you can get a pack for about $10.
