I think that would help.
At the moment, we are not sure what you mean by 'small'.
You've indicated that they are so small that they would not even fit on a baby or a doll.
(Assuming they are for pierced ears) is the post long enough to fit through an adult ear?
If not & if they were advertised in women's jewellery, then I think you could have a case of not as described because if they are earrings for babies or small dolls & would not fit a woman or young girl, I'd expect an ad to be clear on that.
But if the post & backing is an average sort of size & it is just that the huggie design itself is much smaller than you expected, then you probably would not have a SNAD case as they would indeed be 'small huggies' as described.
When someone is selling anything like earrings, they do tend to get up close to the item when taking a photo, so as to show the detail. Without something else in the photo to give perspective, it can be hard to judge actual size. I do think the seller was a bit remiss not to put a ruler, coin or cm measurement in the listing. Technically it may be an item exactly as described but it is still a poor ad by omission.
