NOKKO Rulers Bulk for Classroom - Pack of 50 - Clear Plastic Ruler 12 Inch / 30 cm - Transparent School Ruler with Inches and Centimeters - Back to School Supplies for Kids, Students and Teachers

My students prevent errors by being able to see through the ruler as they measure something or are drawing lines as needed. Inexpensive to replace and does what it needs to do. MM and inch scales are perfect.

I wanted to test the durability of these since they said they could withstand being bent. I could not break one, which doesn't mean my students won't be able to but I was impressed. Very flexible. They were easy to read and I like that they were clear in color. Very good quality.

Bought to donate to children less fortunate in the Caribbean.

They look fine and should hold up. I teach 8th grade math and don't use them that often. We'll see.

Great value. They are thin and easily break, but they are cheap enough to replace easily.

They are thin but less likely to snap and bend.

I would buy again - great value for the money and really good rulers. However, the first day using them one student shattered his ruler when it twisted in a desk crack. So I experimented with one and found that if twisted a bit when bending, the ruler shatters into sharp shards. With that caution added, they are still a good buy, and very handy to have available.

I like that it has flex to it so it will make it harder to break
