Note the container they come in has a lid that doesn't fit the container well. So after removing the plastic, make sure the container is on a flat surface or you'll be collecting stainless steel pins forever unless you have a big magnet. I have a Mini Frankford Arsenal wet glass. I only used half of the steel pins that come with this container. I also used Frankford Arsenal cleaning solution (2 caps per load). The brass was pretty dirty and they looked brand new. I recommend this product for use in your wet glass.
