As their name indicates, these interesting addition to the Tangle range are…..Flat. This is what your Tangle Jr. would look like if you flattened it out. Still with all the properties of a classic Tangle and able to coil up and twist the same, the Flatz has squared edge sections that add a natural additional tactile feel when it twisted. These Tangle Flatz are no longer in production, so these are probably some of the last available anywhere. As they say….when they are gone, they are gone. Not suitable for children under 36 months due to small parts.
