“My favorite was The Idolmaster! So I bought from here again and the packaging is so good, just as expected. It arrived safely, but it took a day or two longer than the estimated delivery time, unfortunately. I’m a very impatient person and couldn’t stop checking the tracking updates – LOL! But that’s okay.”

Frequently Asked Questions
Is The Idolmaster merchandise on onemall.jp authentic?

Why was shipping more than the item?
Small, low-cost collectibles can carry higher relative shipping because international couriers price by weight and size; consolidating several items into one shipment lowers the per-item cost.

Are there import duties?
The US $800 de minimis exemption was revoked on August 29, 2025, so US shoppers may owe duty on imports[2].
