The Lyman Replacement Mica Refill (Lyman part no. 7991415) is a 1-ounce top-off of the mica additive used with dry tumbling media to help polish brass and reduce media dust while cases clean. Mica acts as a light dry lubricant within the tumbler media, and over repeated cleaning cycles the supply gradually depletes, so a small refill keeps your existing media bag performing the way it did when new instead of buying a full new batch of media. This is a simple, inexpensive way to extend the useful life of your current tumbling media.

Key Specifications

• Packaged as a 1-ounce refill size.
