WorldwideKids English Stage 4, Disc Set #19. Purchased in 2014, official product. #FUK Discount OK ⚠ Playback confirmed. However, disc #16 skips, so it is considered junk. Therefore, I will include a "playback-good, home-stored disc" of #16 for free (as a bonus). Discs #20, #18, and #17 are sold out and not available. Please understand this before purchasing. ● The other discs played well at my home. I do not guarantee playback on all devices. ※ This is a copyable product, so returns are not accepted.
