This is a set of 15 brand new, unused mirror wall stickers. These mirror wall stickers can be applied without damaging your walls. They can be easily installed anywhere you have a surface to stick them, such as walls, hallways, bathrooms, toilets, kitchens, and entryways. To use, simply peel off the backing and stick them wherever you like. There's adhesive on the back, so you don't need to prepare anything. Also, unlike mirrors, they won't break, so they're safe for homes with small children. The set includes 15 sheets, each measuring 15cm x 15cm. The third photo shows the actual product. The blue color is a protective film. Please peel it off after application. You can also cut them to your desired size and shape using scissors or a cutter, allowing for creative arrangements. We plan to use simple packaging. Please refrain from purchasing if you are concerned about this being a foreign product.
