Review: ok product, deformed by packaging - these are thin pieces of clear plastic and the measurement marks are ok. But they are delivered folded in a plastic bag smaller than the ruler plates. The result is we received five of these all with permanent folds that will never lay flat. It can do the job if you press down, but there are other options which probably know how to package their products.
Review: En las especificaciones dice que es de plástico delgado y flexible. En realidad parece una hoja de lamina de acetato. Demasiado 10 dólares por una hoja de lamina de papel acetato.
