One location of Tokyo Japanese Lifestyle, a chain store in California, has this posted in a display case with their figures. It looks like they used the same images. The fake sticker explanation goes along with the example you posted, Bran. You can see where it says "ソ" instead of "ン".
Something I find funny, is that the one location I found this sign at is selling authentic import merchandise with the stickers, while other locations that do not have this posted, are selling a mixture of bootleg and authentic merchandise.
