Generously sized, 2mm thick and crystal clear, Shinwa acrylic drawing squares have parallax free mm graduated edges with a 5mm/5cm grid ideal for enlarging sketches, marking parallel lines etc.
At the points there are a little stack of perpendicular mm, so you can offset by a given amount and remain parallel - subtle, but it's the kind of really nice little touch you get from a company that cares about what they are making.
