* This Auction for a pack of 250 gm Stainless Steel 0.30 X 5mm Pins.* Media for Magnetic Tumblers that specially made to work with the magnets in the tumbler.* Pins are prepared and specifically designed with special Chromium Alloy Stainless Steel properties and characteristics that will be attracted to the movement of the magnets and yet not rust like steel shot media.* These smaller diameter size of Media Pins are designed to be used with lighter and more delicate jewelry components, like filigree articles and to be able to get inside openings and undercuts during the finishing operation.* When the media is not in use the pins should not be left on the Tumbler above the Magnetic plate, doing so will cause the pins to magnetize, and work grouped rather than separate entities thus reducing their effectiveness and lengthening the work time.* SPECIFICATIONS: - PINS Diameter: 0.30mm. - PINS Length: 5mm.
