Purchased on Mercari about a year ago. Used about 3 times for karaoke practice at home. Wiped down with alcohol wipes. Due to being a used item, there were scratches overall as shown in the photos from the beginning. There were no particular concerns regarding soundproofing or usage, but please refrain from purchasing if you are a perfectionist seeking a new item. The contents are all shown in the images. * Immediate purchase OK * Non-smoker * No pets
