Clearance stock Posh Chalk Pigments Red Magenta is a stunning super shiny metallic pigment. 
A small pot of very fine powder, mix with a varnish or the Posh chalk infusor to create a metallic paint. 
Can also be mixed with waxes, topcoats, and other media (water-based or oil-based) to achieve different effects. 
Alternatively, you can sprinkle the pigment directly onto your project, and apply your sealing medium afterwards.
