With 8 sides instead of 6 and 3 strings per side instead of 4, this Brainstring offers a confounding challenge!
Make a knot, or straight lines, or makes patterns of your own with the nylon strings — holding the polycarbonate orb and grabbing the strings the ergonomic nubs is a joy for the brain AND your fingers!
It'll keep the kids busy for hours - it's like untangling the Christmas lights but they're inside a perspex box!!
