It sticks and unsticks easily in general, you don't have a problem with placement, you just need to not have two left hands. The little imprints of the child are fun, the little one enjoyed the process, and the color came off his hand with a simple wash.

For ME it's rubbish!!! It starts from 40.... approximately centimeters at the bottom end! It doesn't have instructions in general. A printout that simply shows some icons for a paint to put on the child's walls. It gave me a hard time to bring it straight and then I saw that while "I was moving my hand back and forth" to stick the sticker straight without wrinkles, it left white color on my hand and filled it with black lines! In short, after my nerves broke (no, I'm not patient), I removed it, threw it away, and calmed down. I'm not into "fine arts", but I'm not completely clumsy either. If you don't have it and patience, as well as skills, then maybe it's better to look for something else because it's not cheap!

BTW there's an icon that it has for 2 minutes, I don't know what it is. Anyway, for installation, unless you're a Star Trek protagonist to beam it onto the wall, then it's unlikely. ALSO, exclusively and only for installation on perfectly smooth surfaces (smoothed wall, or door, or no wardrobe)
