Review on π Classroom Ruler: Flexible Plastic Straight Edge, Measuring in Inches by Sam Hansen
School use of measuring and marking tools
These are just clear plastic rulers but very easy to read. I've been looking for rulers that start at the bottom to measure certain things in the lab. It looked like the picture, but it wasn't. Measurements are close to the edge but not flat.
Pros
- Impressive
Cons
- Could have chosen a newer model
