Self-adhesive wallpaper, also known as peel and stick wallpaper, is a user-friendly and versatile wall covering option that doesn't require additional adhesive or paste for installation. It features a pre-applied adhesive backing, allowing for easy application and removal without leaving residue on your walls. This convenience makes it an excellent choice for those who want to update their decor quickly and without the mess of traditional wallpaper installation, while also offering the flexibility to change designs as desired.
