Brainstring Original - Recent Toys

Its knot what you think!

The mystery of Brainstring Original isnt just how to untie a twisted knot of strings in the centre, but how it can be that all its strings can be interchanged WITHOUT creating a knot! Four groups of different coloured strings, four strings per group, moving up,
down and around all six sides of a polycarbonate shell beyond just tying or untying a knot, what kind of beautiful symmetries can you create?

Brainstring Original isnt just a puzzle its a work of art.
