The piano is a CT-S200 model. I swear to God, it's like new. It has no issues and comes with all accessories. Its feature is that you can install batteries and use it wirelessly + a bag I bought for it to protect it. I've only used it for about a week or two. Reason for selling: I don't use it anymore. I bought it from Amazon. Its price on Amazon is 689. I'm selling it for 500 with the bag. Note: The bag does not come with it, I bought it separately. Slightly negotiable.
