Casio Casiotone CT-S200 Red Digital Keyboard

This is a red Casio Casiotone CT-S200RD digital keyboard. It includes the keyboard, a music stand, and a power adapter. I have bought it at the end of last year but I rarely used it, and therefore the quality is almost new. I don't smoke, and exchange(ex. exchanging piano with another product) or refund are not possible. The retail price is $180, but I'm selling it cheaper than half of the price.
