Sometimes, bonuses such as posters and photo prints are offered in addition to items sold at CDJapan and they are indicated as External Bonus on the product page. They may cause the packaging of your order to become large.
If you prefer not to have any of them included with your purchase to prevent the packaging to become large, select the following option in "External Bonus Preference" under the "Shipping Address/Gift Options" step during checkout.
Do not include any External Bonus with my order
By choosing this option, no bonus that are offered in addition to items will be included inside the package, regardless of how small or thin the bonus may be.
