The BD Sharps Disposal by Mail container holds up to three hundred pen needles or lancets, or up to one hundred insulin syringes. The kit contains a purple wrapping bag and a postage-paid mailing box. Place your used insulin syringes, pen needles and lancets into the container. When the sharps container is full, seal it. Place it into the purple bag. Then location the bag inside of the mailing box. Fill out the tracking sort and preserve a copy for your data. Give the closed postage paid mailing box to your mail provider or bring it to the post workplace. When the mailing box reaches the remedy facility, the tracking sort is scanned and a certification of destruction is mailed back again to you, confirming the destruction of your sharps container.
