Ruler - 17 cm New, unopened. The adhesive on about half of it is slightly weakened. My child kept it carefully. It's very easy to see, so it's perfect for young children. 17 cm is the same width as an elementary school notebook! It's just right for drawing lines, and you can draw them neatly without worrying about the edge falling off. It's a rare size, so I'd be happy to pass it on to someone who likes it. I hope children who love cars, such as fire trucks and ambulances, will use it ♪
