I added these page poppers to 8x8 pages in books for my niece, 12 and nephew 8. They loved the interactive pages in the C-Line - Memory Book - Page Protectors - 8 x 8 Clear - Combo Kit. My nephew especially enjoyed watching himself "pop" off the page!
Years ago (1999) I placed my LO for a contest and won 2nd place using Page Poppers and page protectors. It was alot of work and the product is durable and easy to use.
