I only used it for about 30 minutes a day for about a week. It produces a beautiful sound, but I recommend replacing the strings after purchase. The entire body is in really shiny and beautiful condition. I have never bumped or dropped it. I don't think there's any warping in the neck. Images 6 and 7 are more vivid than the actual item, but the actual color is a deeper blue. Image 13 is closer. The sides and back look black at first glance, but they are a dark blue. I fell in love with the color and decided to buy it. In image 8, there is some cloudiness, but the transparent protective film has not been removed. I will include the accessories and YUI's sheet music. If anyone would like to use it, please consider it. Color: Oriental Blue Burst
