Sinus Tap was invented by Kim Carey BSN, RN, a registered nurse for 25 years, after her own struggle with sinus congestion. Sinus Tap is a handheld device used to gently tap your sinuses to help loosen congestion and move mucus out. A natural, holistic, non-invasive approach to relieve sinus symptoms without the use of medication, flushes or sprays. No batteries, cords, or chargers. No side effects or adverse reactions. TAKE ANYWHERE, TAP ANYTIME!!
