This and the black cap are both good for both flowers and concentrates. The difference between the two is in style and color, not function. The design ensures that you will be getting only the herbal flavor you are looking for and that you won't be inhaling any butane fumes. It comes with an L shaped hex wrench for easy disassembly for cleaning.
A debris screen is installed in the cap to keep the interior clean, which is especially important when using water pipes.
