I bought two Olypas, one was an assortment of five opened packs (original price 9800 yen, probably packs I don't need). The other one was a confirmed SR, but it was an N+RRR, which was different from the description, and I asked to return it, but I couldn't, so I tried tidings to the management.
I was surprised when I heard that it was sent through the mailbox, although the product was listed as registered and recorded.
I was surprised when I heard that it was sent by post, but I am glad that it arrived safely.
The shipping method of the product can be a cause of dispute, so please be careful.
