Colloidal Silver Artisanal Natural Refill 40ppm 300mL Made in the UK. Our Colloidal Silver boasts a composition of 10-20% ionic and 80-90% colloidal silver. This product is meticulously crafted using only purified water and top-grade silver. We prioritise high-quality ingredients that undergo rigorous testing, ensuring a colloidal silver you can rely on. These naturally occurring, petite particles are pivotal as their diminutive size grants a larger surface area per volume, amplifying the silver's efficacy. We offer 3 sizes tailored to your needs: a handy 30ml spray for on-the-go use, a generous 100ml family spray, and a 300ml refill bottle compatible with both sprays. Why is ours better? Our colloidal silver are green manufactured which makes them not use toxic chemicals which can cause adverse side effects when it comes in contact with the skin. Who can use? Perfect for home use, while on the go, or during travels. An excellent choice for self-care, caring for family and friends, and even suitable for numerous pets. A valuable enhancement to any home.
