Medium triangle wall decals/stickers. All our wall decals are so easy to use - they simply peel off the sheet and can be stuck directly on your wall or surface. They instantly make a plain wall look that bit more special and can be used in rooms throughout your home. Each A4 sheet contains 36 decals of approximately 1.5" in size. Please select colour choice from the drop down menu. Please note that these decals should not be stuck on to freshly painted walls and surfaces, allow a week or two for the paint to cure.
