T-SQUARE band score. It seems to be quite inflated compared to the original price. There are no writings or folds, and it's almost in a clean condition. However, since it's been a few years since I purchased it, I've marked it as having no noticeable scratches or stains. After researching it myself, I've determined that it has considerable value, and I'm listing it at a price more than double the original price. However, I want to sell it to someone who needs it. I have further reduced the price from the time of listing. Thank you.
