Next time someone tells you that building bricks are only meant for children, you’ll have the perfect counter-argument: the Building Bricks Keychains. These colourful key chains are not only a nice childhood memory, they also help you to distinguish and organise different keys. This works due to the included building brick strip, which you can attach to your wall with the adhesive strip on the back. After that, you can put your four different colourful building bricks up there.
