This English learning DVD set for young children consists of 5 discs, with each stage ranging from Level 1 to 4, plus a step-up disc. I am selling a used set that was confirmed to be working about 10 years ago. *Bundle discounts are available.* I bought these because my child repeatedly watched the Worldwide Kids trial DVD without getting bored. However, since I'm not good at English, and I kept the DVDs out of reach when my child was a toddler to prevent scratches, I haven't confirmed that all the DVDs can currently be played properly. I will be listing each stage separately, but because there are many DVDs, it's difficult to check them all for playback. Therefore, I am selling them at a significantly reduced price from the original purchase price.
