^^^ That post was from an authentication request but I just found another odd one that makes me wonder why the term was that they searched.I think Japanese seller use a translation program to help with their listings.
"Matthew Healy" and "grabtan" are among the terms they seem to get. I can't think of others right now, but there are several seemingly random words.
Search ebay for the key words and find (mostly) Japanese listings. (Other sellers may find those terms and use them too but it's a predominantly Japanese thing.)
This listing's title is "COACH Vintage Leather x unborn calf Handbags used Red Tote Legacy/Japan"
Unborn calf??
And in the description, they call the texture, "brushed texture unique to pony leather." Pony leather?
