Volini Spray is a pain reliever that works quickly to relieve muscle pain, sprains, and joint discomfort. Volini Spray contains microparticles that provide rapid pain relief by penetrating deeply and is scientifically prepared with chemicals such as Diclofenac diethylamine, Methyl Salicylate, and Menthol. It can also be used to treat musculoskeletal and joint discomfort. The spray nozzle has two seals on it. In addition to a small seal on the lower side, there is also a huge seal right above the sprayer. The seals will pop if you press down on the lower side with your thumb or index finger.
