Hello.

I found several listings on Aliexpress (which I guess is already kind of a red flag) by this seller Gagagallery Collectibles Store (I hope linking to external sources is permitted on this forum: if not, I'm sorry) on autographs I am interested in (that is, from manga artist Takehiko Inoue).

I would like to ask your opinion as for the possibility that any of these are real, though I'm quite certain they're not. All of the items (supposedly) signed by Inoue are listed with the same (very low) price and by the same description. Also, for some of them there is more than one available.
Trying to do my (though limited) due diligence, I asked the seller for some kind of proof of authenticity. His answer was as predictable as it was discouraging and this is a direct quote:

"Dear buyer， Thanks a lot for your appreciation. We have stable and friendly cooperation with media friends for more than 10 years and we guarantee it is authentic not copied or reprinted . We can not offer certification for the item because there is no agency in China . Deep apologies for that. But please do not worry about that, we guarantee 30-days-return-refund- policy of our Aliexpress store (gagagallery) if you are not satisfied with your order.  Feel free to contact us if you have any questions or problems. Thanks in advance Gagagallery"

In light of all of this, I'm asking if anyone more experienced than me can confirm my already more than stable conclusion: this store is just a scam. I'm going to attach a couple of pictures of their "products", just for good measure.
