DisneyWorld of English Step by Step 12-Volume Set

Thank you for looking.
This is a complete set of 12 Blu-ray discs for the Disney English System (DWE) Step by Step program.
As this item has been stored for a long time, there are some issues with the cases and discs, but all discs have been confirmed to play. We are offering this at a low price for those who prioritize usability.
[Set Contents]
• Step by Step Blu-ray Volumes 1-12 (Complete Set)
[Product Condition (Please be sure to check)]
• Discs: As shown in the first photo, some discs have wavy marks on the edges and scuffs/scratches on the surface (the cause is unknown).
• Cases: As shown in the second photo, some volumes have damage such as cracks, splits, and peeling due to age-related deterioration.
• Playback Confirmation: All 12 discs were confirmed to play from the beginning on my home player before listing.
[Notes]
• Due to overall signs of use and damage, this item is intended for those who prioritize practicality and are looking for a usable set for their child's English learning, rather than for collectors.
• Playback on all devices is not guaranteed. Please purchase only if you understand that this is a used item and is being sold as-is.
• The item will be lightly cleaned, packed with cushioning material, and shipped.
Immediate purchase is welcome. Please feel free to comment if you have any questions.
