They do the job
Recently painted the bathroom in a different colour, and had a slim line of tiles with small blue squares. Eventually the tiles will be replaced, but until then these do the job nicely. Cut each sticker tile into three strips, and stuck on top of the blue tiles. From a distance it looks great, you would never know they’re not real tiles. Close up you can easily see they’re stickers though. Have stuck on great, even in a bathroom.
