About USED Items

Please note that these are pre-owned items and are generally in typical used condition.

They may show some signs of wear, including minor scratches, fading, or general use.

Images & Accessories:
Since we have multiple copies in stock, the product images are for illustrative purposes only. Unless otherwise stated in the product title, accessories such as Obi strips, special bonuses, or tags are not included. Even if an Obi strip is shown in the images, it may not be included with the actual item.

For Books: There may be some signs of use such as bent corners, scuffs, or mild sun fading, but nothing that affects reading or enjoyment.

For CDs: The case may have cracks, but the disc itself plays without any issues.

Digital Codes: Any included product codes or download codes are likely already used and cannot be redeemed.

Important Notes

If you are very particular about the visual condition, we kindly recommend refraining from purchasing.

To keep our prices as low as possible, we do not provide additional photos, as preparing them requires extra labor costs.

If you are specifically looking for an item in excellent condition or with a tag/Obi strip, please contact us before purchasing.

We will do our best to find a nice copy, though the price may be slightly higher depending on availability (or it may not be available at all).

Thank you for your understanding.
