Japanese 45s were released with standard orange labels for commercial releases with either a single or double sided insert as a sleeve.
All commercial releases have equivalent promotional white label variations with the same art work as used on the original release.
Japanese EPs have a standard carton hard cover with an insert. Some have a gatefold sleeve as well. The label design is standard white and orange with a closed spindle hole. A few Japanese test pressings exist all with b&w covers.
