For Jujutsu Shenanigans (JJS) , buying 50 emotes costs 1,000 Robux according to the game’s emote pricing pattern shown in a fan wiki source, which lists 50 emotes at 1,000 Robux.

Quick read

  • 50 emotes = 1,000 Robux.
  • That same source shows the pricing scales as 1 emote for 25 Robux, 5 for 115, 10 for 225, 25 for 550, and 50 for 1,000.

Note

The JJS wiki also says the in-game currency $ is used for emotes and other shop items, but the exact $ price for 50 emotes is not stated in the source I found.

TL;DR: If you mean the Robux bundle, 50 emotes cost 1,000 Robux.
