Semenawa ropes are for sadistic sessions. Here the desired qualities are quite the opposite to the usual shibari rope criteria. Fibres such as palm hemp and coconut are chosen specifically because they are scratchy, prickly and generally uncomfortable...especially in sensitive areas.
As these lines are ordered in small batches, they tends to be some variation in what is available at any time. So if anything tempts your sadistic side, grab it while you can.
