Review on 📏 Maped Twist'N Flex Ruler 12 Inch / 30cm - Assorted Colors: Unbeatable Flexibility and Versatility (279010) by Sasha Hsiao

First of all very nice graphics on this puppy: high contrast, good choice of font. It also appears to be very durable. If you just need rulers and maybe some good edges for say a geometry lesson then these are great. If you want the edges to be perfectly straight, look elsewhere. Edges are misaligned/cropped. The ruler marks (black lines) are slightly offset from the edge, causing your drawing tool to run unevenly. You will never draw a straight line with these edges. Luckily it's not very expensive so I'm keeping it to myself although I only bought it because I needed good straight edges that wouldn't wear out quickly.
