3.8mm Flat Back Crystal Setter Punch with Multi Pack of Birthstone Crystals (240 pieces)

3.8mm Flat Back Crystal Setter Punch with Multi Pack of Birthstone Crystals (240 pieces) NOTE - This setter works best on very soft metals like Aluminum and Pewter. Because you have to move so much metal (and create a solid impression), it is tough to impress in harder metals, especially if they are thin. Crystal flat back size SS16.  12 packs of 20. 3.8mm in diameter. This was made to create a divot in metal for our 3.8mm flat back crystals to sit in. Tool is made from 1/4" square heat-treated tool steel. It will arrive with a slight coat of oil to prevent rusting. Wipe oil away with a paper towel, do not use water.
