An extremely unique design, our Bio+ has its own built-in funnel. As we all know often times after rolling, there is weed and kief all over your tray. If you are smoking the gas we know you are the leftover weed that may get stuck to your hands and can be difficult to get back into your grinder and jars. With the funnel attached to the Bio+ users will have a significantly easier time putting their weed back into their storage containers.
