Flexible Shatterproof Bendable Unbreakable Safe Soft Transparent Clear Plastic Straight Flat Ruler, 30 cm/12 inch. Set of 2, Clear and Blue, for Home, School, Office, for Kids and Adults

I bought these to replace a hard to find thin plastic flexible ruler. These are not particularly thin, but they are very flexible. They also are very clear, which can be very helpful!

Got 2 blue rulers, instead of 1 blue, 1 clear. They are flexible, but quite thick. Not easy to read through. Not worth my gasoline to return, but BEWARE.

U got two blue, the girls had to mark them to tell them apart

As the title says, these worked great on a bright background. However, if you have to measure anything without a background (for example - holding it up in the air to measure something) its nearly impossible to read. I also hate any measuring device that doesn't start with the edge of the ruler so you cant use the edge of the ruler as a starting point. That's my fault for not noticing though. End of the day, it does the job,

I like that they’re flexible and transparent, but the blue is too dark to see through & they’re missing the longer marks at the 1/2Inch mark that most rulers have that’s super helpful to me because I don’t want to count the little lines to figure out where the 1/2 inch is every time. So I would not recommend these rulers to anyone!

Not useful for in the field use. Too flexible. Heat conditions don't help

The error over the 12 inch scale was short by 1/32 to 1/16". So, might be accurate enough if you're just using a couple inches of it. Nice flexible material, but worthless as a ruler.

These are perfect for my application.
