This is a 50cm flexible curve ruler. I am selling it because I mistakenly bought it thinking it was a straight, rigid ruler. This ruler is highly flexible, making it suitable for measuring full-scale curves or drawing approximate curves. The scale starts at 0. It's convenient for measuring large items like men's clothing or the circumference of bags. Please note that it will be slightly bent for packaging when shipped. #ruler #measurement #menswear #50cm #hat #bag
