Yes, this shower curtain is compatible with the Spirella click system, as all Primo models are equipped with sturdy eyelets that fit both classic shower curtain rings and the Spirella push-button system (click system). The exact compatibility with the click system is confirmed for the Primo series, even if the size 180 x 180 cm is not explicitly mentioned in the official product descriptions, but the construction and eyelets are identical for all Primo curtains.
