Pardo Mica Clay from Viva Decor is a premium polymer clay made with beeswax. There are 5 metallics in this line. There are also another 8 metallics in the Jewely Clay line. While not as bright as the Cernit metallic line, these are very nice colors.
This is a very nice clay and can be worked very thin. It can be somewhat stiff until it is moving, and it is recommended that you warm it up in your hands before rolling it out. It is free of odors when baking and doesn't leave residue on your hands. It is also a slightly different consistency than the translucent colors, and easier to condition. It starts out stiff but warms quickly in your hands.
