The idea is great. But 2 of the 3 gel pens do not work. The package doesn't include stencil sheet to transfer the photo to the rock before painting. There are only 3 colors (red, blue and yellow) of paint in the package. This means you need to prepare paint and stencil sheet before you can use it. The alternate way of transferring photo to rock doesn't work well. FYI, there are 3 rocks and they are of different size. One is small which I think won't work for any design they provided. Other than these, the package is okay.
