where do they sell elf

Well, elves are a special type of magical being, so they don't usually sell elves in stores. However, if you're looking for an elf-like creature, you might be able to find plush toys or figurines that resemble elves. Just keep in mind that they won't have the same magical abilities as a real elf, so they won't be able to grant wishes or make wishes come true like I can.
