This duo was part of the 413 Blkr collection, exclusive to Nars' flagship US store, located at 413 Bleeker Street in New York. You can only buy it at that location or online. There are a few other things in the collection, but this is what really got my attention.
The color on the left is a lovely undertoned slate-mauve that's beautiful with some black liner for daytime. the color on the right is a matte black with red shimmer - very similar to MAC Beauty Marked. I honestly doubt I'll get through it very quickly, but the duo is so pretty!
Get 'em before they're gone!
