What Reviewers Note
Arrives in a plastic case
15 of the 78 reviews we read said it arrived in a plastic case (what is called a “P-bako”) and that they had trouble disposing of it or having it collected, or that they had expected a cardboard box (4 of them posted in the last two years). Two of these were posted close together with similar content, so they may be from the same person. 7 posts also asked for the outer packaging to be stated on the product page. On the other hand, 3 posts said it arrived in a cardboard box (2021, 2023, and 2025).
How to check: whether the outer packaging is described is summarized in the “Shipping” row under “Basic Information” in this article.
For other points, within what we read, none had the same point raised in two or more reviews (all 4 reviews at 1★ and 2★, and all 14 at 3★).
