Review on O'Lipfa 66636 Ruler with Lip Edge, 4-inch by 36-inch by Jessica Lewis

Terrible. I cut a lot of fabric so I had high hopes for this line. Also bought a large cutting mat. Revain was blown away by the quick delivery. The length of the ruler is 1/4 inch. This is plexiglass, like all the other lines. They are heated and then folded at one end so that end hangs down and slides over the edge of the cutting mat, giving the straight edge more stability. The problem is that they bend it crookedly. This negates any benefits of the lips. If you still need to keep the ruler straight, it's just like any other. Sent back first, received second. IT WAS WORSE. The first photo was ordered first. The second and third were the next (spare). How could the manufacturers not know about this? There is an idea to make your own. It's just useless.
