I purchased the Disney English System (DWE) through official channels. * Songs Guide 1-12, 4-book set Since I haven't used them, they are in good condition. They have a slight warp from being stored upright. If you need additional photos, please let me know in the comments and I will take them. I am also open to combined purchases with other items I have listed. Feel free to comment. I want to sell these, so I am open to price negotiations (but not significant discounts).
