Can you reach out to the user who bought the item I want?
Fleamarket sites protect the identities of auction winners and other shoppers. We have no means and can't reach out to other shoppers who have won/purchased the item you want. Doing so could also be considered cyber harassment, which could result in our shopping account being blocked or even banned by the website.
We instead recommend you check to see if the item can be bought elsewhere by using its Japanese title as keywords for searching.
