Does not ghost, as stated, when using the included marker. Other markers may ghost, but this can be removed with rubbing alcohol.I made my board portable by mounting the decal on Eucaboard fiber board from Lowes.
The board was easier than I thought to install. The board works great even though I have it on a spackled wall.
Easy to clean and grate for anywhere needed whiteboard
Easy to install, graph lines on the back makes it easy to cut staight lines if you need to piece out into sections.
Had to lecture a few times during vacay and this worked perfectly! Stayed on the wall and left no marks or sticky residue. Highly recommend!
