This item is from about 15 years ago. It has been stored in a dark place. Although it hasn't been used much, it's quite old. Name stickers were attached to each card. I removed all of them, but as you can see in the image, there are marks left. There may be slight stickiness. Also, the urethane building blocks have some staining.
