Features 1. **Materials:** The Square Cube Prism is made of excellent, durable, and clear optical glass. It is textured for better refraction and clear reflection. 2. **Unique Craftsmanship:** The glass prism features a six-sided polishing process, resulting in an exquisite and beautiful design. Different angles in the same environment will produce completely different color effects. 3. **Portable Design:** The small size of the glass prism allows you to easily hold it in front of a camera lens for special photos. It is also easy to carry without taking up much space. 4. **Functionality:** Glass prisms are used to appreciate beautiful optics and for experimental light synthesis. They split a light beam into different spectral components, displaying them as rainbow colors. 5. **Wide Application:** The glass prism can be used for teaching light spectrum physics or as a research tool. It is also suitable for decoration and photography, producing good filter effects. It makes a creative gift for children learning about the physics of light.
