What are 'pins' used for in the cleaning???

They are stainless steel pins small enough to clean primer pockets and inside the case. When buying the Frankfort Arsenal rotary wet tumbler it comes with 5 pounds of pins and a shining solution for the water. Brass comes out looking brand new. The Frankfort Arsenal magnet will pick up the pins in the water and elsewhere. Using the Frankfort Arsenal media/case separator dumps the pins and water into a bucket keeping the brass separate for drying. Their brass dryer looks great but pricey.
