It was a big mistake that I did not open this item right after I received it. When I finally did it was past the time I could return the item. They sent me a broken and returned sphygmomanometer. The glass that contain the mercury was broken and is inside a ziplock bag!!! But I cant return it anymore. The seller is AmericaRX.Get more detail about Desk Mercury Sphygmomanometer by MDF Instruments Direct, Abyss - 1 Ea.
