These little building block strips are awesome. They are very flexible with mounting tape attached. I put some on the wall in my bathroom and added blocks to it to created a toothbrush holder for the kids. The tape seems to hold well so far. I also wrapped them around a flower vase and added a decoration woth blocks that could easily be change with the arrangement each time. These have so many uses and gets you thinking about ways to be creative. Great for all ages.
