The Pen Emote in JJS appears to be obtainable by a limited number of players, and one source says it was “owned by the first 100 people” who got the related Nep achievement through a secret code. Other sources suggest the unlock is tied to a public-server boss/quest chain, but they do not give a clear total beyond that limit claim.

What that means

  • The most direct number I found is 100 people.
  • That number looks like a cap for the original unlock window, not a confirmed live player count right now.
  • Community guides and forum posts describe the quest steps, but they do not provide a verified updated count of current owners.

Clean answer

If you mean “how many people can have it,” the best-supported answer is 100. If you mean “how many currently do,” I couldn’t verify an exact up- to-date count from the available sources.
