Buying
Tags, packaging, reissues and the counterfeit question. How to tell what you are actually getting before you order.
Most Sanei stock reaching buyers outside Japan is imported in batches by third party sellers rather than distributed through a single channel. That produces a lot of variation in what arrives, and a handful of checks cover almost all of it.
Genuine figures carry a tush tag with the maker name and a hang tag with the character and catalog code. The tush tag is the one worth looking at, since hang tags detach easily and get lost in transit. If a listing has photographs, the tag is usually visible in at least one of them.
Japanese language tags are normal and expected. They are not a sign that something is wrong with the item, only that it came from the domestic run rather than an export run. The plush is the same.
Fakes of the popular characters circulate, mostly Pikachu and Kirby. The reliable tells are in the face: printed rather than embroidered features, eyes that sit at the wrong spacing, and colour that is close but a shade off. Fabric on counterfeits tends to be shinier and thinner, though that is hard to judge from a photograph.
Price is a weaker signal than people assume, since legitimate imported stock swings widely depending on when a seller bought it. A figure being cheap does not make it fake, and a figure being expensive does not make it genuine.
If you care about keeping the item mint, check whether the listing specifies sealed packaging. Imported plush often ships in a clear polybag rather than a box, and that bag arrives creased more often than not. For a display piece this is irrelevant. For resale it is not.
Reissued characters are not usually labelled as reissues. Where a figure has been produced across multiple years, the catalog code in the listing title is the thing to match against what you already own. If the seller has not listed a code and you need a specific run, ask before ordering rather than after.
Imported stock moves in batches, so availability gaps are normal and estimated dates shift. A listing showing a date several weeks out generally means the seller is waiting on a container rather than that anything has gone wrong. If a date matters, for a birthday or similar, buy from stock that is already in the country.
