Italian-made, ISA Shower Heads have a reputation for quality that is second to none. They feature three entirely different and refreshing spray patterns. Another winning feature is the “fast-clean” anti-scale system. The blue gasket is made of a flexible silicone which is very elastic. You will no longer need brushes, sprays or abrasive cleaners. All you need to do is gently rub the blue silicone nipples with a sponge, or by hand, and any lime build-up will simply fall off. Brilliant! Quality and Economy. We think it’s a winning combination.
