kidsline ones are wallpaper not removable/reusable ones.....we have one in our boys room. you have to peel off the top vinyl layer then soak the uinderneath paper bit in warm soapy water using a sponge or similar...... when it is fully wet you can scrape it off with a paint scraper...be careful with the scraper not to dig into the plaster and it should come off nice and cleanly...then just wipe the wall down and voila!!
