Thank you for viewing. This is from about 8 years ago. There is a risk of wrinkles if glued. I opened it, but in the end, I never used a single sheet and it was left unused. 15*15 color cellophane 5 colors, 12 sheets total Red: 4 sheets Yellow: 2 sheets Blue: 2 sheets Green: 2 sheets Clear: 2 sheets How about using it for crafts, dioramas, or science projects?
