Take a focused look at the specifications and what they mean in practice. In this video, we demonstrate the 150x150mm self-adhesive PETG mirror designed for educational use. You'll see how its unbreakable, food-grade PETG material ensures safety during children's science experiments, watch the easy peel-and-stick installation process on various surfaces, and observe its optical clarity in real STEM applications like kaleidoscope building and light reflection activities.
