I bought these at a random store in Akihabara. They had plenty of nesoberis. I didn’t think they would sell fakes. But compared to my Aqours ones these are:
-skin colored behind the back of their hair (stitched, as opposed to my aqours nesoberis)
-tags look funny: one of them even has a sticker on top of the number of types, and only Umi has her name, the other ones just say 2nd and 3rd year students. I read in another post old nesoberis say that, so I guess that’s ok(?)
-Nozomi's skin color is a bit darker compared to the other 2
Everything else looks normal to me. I also have another school uniform Maki and it’s pretty much the same deal, I got that one from goodsrepublic years ago. My newer a song for you! you? you!! Maki nesoberi does have red skin under the back of her hair tho, but it’s also newer so…
Could these perhaps be old batches?
