Essential Scratch System
Hurry! Last few remaining
Itchy eczema or psoriasis? The Essential Scratch System gives you two itch-beating sensations in one bundle — the satisfying fingernail-like scratch of the Scratch Star, and the gentle cooling massage of the Scratch Attack Roller. Together, they form a winning combo to cool itchiness, reduce redness, and distract from scratching with bacteria-filled, damaging fingernails. Plus, the protective case keeps your Scratch Star hygienic and fridge-ready.
