Need some reliable rulers for the kids' homework, your office projects, or just general crafting? This 4-pack of clear blue plastic rulers has got you covered. Each one is a full 12 inches (30 cm) long, with a nice slim profile that's easy to handle and store in a pencil case or drawer. The cool part? They're dual-sided – one edge has inch markings, the other has both centimeters and millimeters, so you can switch between measurement systems no problem. The markings are printed in high-contrast black against the transparent blue plastic, which makes them super easy to read without straining your eyes. They're made from sturdy, flexible plastic that can take a little bend (handy for measuring curved surfaces) and won't snap easily. The set also throws in a bonus white soft ruler for good measure. Perfect for students, teachers, artists, engineers, or anyone who needs to draw a straight line or take quick measurements. Whether it's for geometry class, scrapbooking, or marking up documents, these rulers are a practical, affordable staple you'll use all the time.
