Heart Prism (holographic) 6" 5 Sheets
These 6" squares of holographic plastic film are a bit tricky to fold at first, but once you get the hang of it, they make neat models that reflect light in dazzling patterns. This package contains 5 sheets (one each of red, blue, yellow, green, and pink) each with a reverse side of silver.
