The Marusho & Co product number for the Ginga stickers range they made (bookmark, prism and seal set) is 136号
They were originally 20円 (yen) each, and described as having 30 attached per bundle (though some do have more than this). Like the other Marusho merchandise, some of the stickers have the “Lucky” stamp on the backing you could take back to the store and exchange for another.
There are 25 of these stickers to collect. They are called ‘Seal’
シール on the packaging; this is a term still used for stickers in Japan.
