Children ages 8 to 12 are the target audience for CrunchLabs Build Boxes, although many other children and adults have also found them to be fun. Every product is put through independent testing to make sure it complies with US and EU safety regulations for children 8 years old and older. Parents and guardians can decide whether something is age-appropriate for their children, but Roger's has made a lot of effort to guarantee a consistently enjoyable experience for the target age group.
