With 8 sides instead of 6 and 3 strings per side instead of 4, this Brainstring offers an even more 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!
