I can confirm I too ordered off animedakimakurapillow.com who, despite the social media YouTube hype, are Chinese counterfeiters and avoided by genuine collectors of licensed Japanese made dakimakura.
My pillow case is unusable as this company's products are 148cm x 46.5cm! (see attached photos at end of review) The standardised size of dakimakura pillow inserts (and covers) is 150cm x 50cm.
Shipping was horrendous "snail mail". They said they were using DHL express but my parcel arrived by standard Royal Mail Postman and their tracking didn't work. I paid $89.99 which included "free shipping" but the quality of manufacturing and shipping were awful (took exactly a WHOLE MONTH to arrive).
As a comparision I ordered something off kanojotoys.com. A Japanese company with Japanese made products. Theirs arrived international post within 6 working days, for the same price as animedakimakurapillow.com!
(Pro-tip kanojotoys.com sell authentic Japanese made dakimakuras, but it was too late for me to notice).
Measurements of my "150cm x 50cm" came in at 148cm x 46.5cm making my pillow look warped and too skinny. Look at my photos here exact same shortened measurements as corner cutting as Ha C.

The sponsored YouTube reviewers get provided with a flimsy, sparsely filled floppy feathered pillow to fit theirs but you can tell they got sent better made review pillows to make animedakimakurapillow.com look good, that aren't representative of what the average ADP customer gets.
They don't look as skinny as mine or the other 1 star reviewer. You don't get a bag or anime keychain either.
So yeah these reviews are bait and switch tactics.
If you want a decent guide on where to get a genuine Dakimakura and avoiding counterfeiters this guy is an experienced collector of japanese dakimakura. He even goes as far to call out animedakimakurapillow.com by name and calls them out as chinese knock-offs.

For $100-$150 you can purchase a genuine Japanese made dakimakura from Japan as it should be.
Animedakimakurapillow customer service, had this to say when I confronted them with the photo proof.
"I checked and confirmed with our team that we have indeed sent out the correct size for your
Pillow Cover. Also, our sizing method is standard as the purpose of the allowance is to give the cover a snug fit over the insert for a full volume look so the cover won't wrinkle easily."
Anyone can see that is BS. 150cm x 50cm is the international standard pillow insert. A counterfeit pillow case measuring 148cm by 46.5cm will not fit. There are no retail body pillows of that warped size or dimension either (I did check hence actioning a refund request from ADP).
You have been warned.
I ordered a modification for a Dakimakura I have and the shipment came in faster than expected. Furthermore the product was excellent quality and I am overall satisfied with their business practices. Their email newsletters have tons of deals every day so there is always a good time to get something from Animedakimakurapillow at a good price. I would recommend this website for those interested in the anime dakimakura for their room!
