Magnify ray use

Doraemon uses the Magnify Ray in The Nobi Family's Giant Tunafish.


  • In the early manga, it has the same design as the Small Light.
  • The original height the user returns to appear to exclude the alteration made by the original gadget, as Nobita was able to return to his original height prior to the use of Devil Card.
