Our growth chart wall decals make it easy to watch your little ones grow - without having to carve notches in the door frames! Forwalls high quality vinyl decals can be applied to almost any surface - painted walls (allow 3 weeks to dry freshly painted walls), wall-paper, counter tops, windows, mirrors and tiles. They will not adhere to cloth, stucco, brick, concrete, cement render or similar uneven surfaces including some wall papers. And when you are ready for a change, removing the decal is just as easy as applying. Gently and slowly peel the decal away from the wall. No sticky residue and no marks and the wall is ready for a new design!
