Checking information on used items: Look for any missing details in the photos and description.

Gather identifiable information.

Please confirm the product name, purchase date, material composition, selected specifications, and included accessories. Avoid using photos of other products with similar names or different configurations as reference. Asking if the instruction manual and original specifications are still available will help you consider how to handle the product after receiving it.

Check the current status

Check the date the photos were taken and the area they depict. Request not only a representative photo, but also documentation that shows the entire item and any areas of concern. If the condition is difficult to discern due to lighting or editing, request additional explanations and avoid assuming that there are no problems if they are not visible in the photos.

Ask about the maintenance and repair history.

Check the supplies used, storage conditions, and whether any repairs or parts replacements were necessary. If there are items you cannot answer, it is important to take that uncertainty into account when making a purchase decision. Don't assume that a product is hygienic just because it looks clean; if you have any concerns about handling it, it's best not to rush into a purchase.

Confirm the post-transaction procedures.

Read the contact deadline, scope of support, and return conditions in advance if you find any discrepancies with the description after arrival. Check the terms and conditions regarding whether the manufacturer's warranty is transferable, rather than relying on the seller's impression. Don't overlook insufficient information or limited support just because the price is low.
