VGMM. Looks like all of these collectibles are exclusive to this Japanese bundle.
"A giant Mario pillow featuring 30th Anniversary fabric, a Super Mario Maker placemat, a Super Mario Maker fabric bag, and a Super Mario Bros. 30th Anniversary towel. Oh yeah, and it all comes in a giant cardboard coin block! The bundle doesn't come cheap, but considering everything you get, it's quite a deal."
