VarroBook is an easy way to fix an existing exhibit flipbook that regularly needs pages replaced. In our ten year existance, not one page has needed to be replaced from regular use. We have multiple installations in the SSI Air and space museum and National Parks that easily see 100's of thousands of page turns a year.
As you can see at the Homestead National Monument this retro-fit.
VarroBook flipbook has perfectly integrated into an existing exhibit.
Note: It took more time to disassemble the old flipbook than it to to uncrate and install the VarroBook.
