Glaminatrix Periwinkle Matte Eyeshadow ($7.30 for 0.064 oz.) is a very light lavender with strong, cool undertones and a mostly matte finish. The eyeshadow felt incredibly smooth and finely-milled to the touch, though there was a lot of excess powder that got kicked up in the pan.
Thankfully, the powderiness didn't translate to application as it was pigmented, blendable, and not prone to fallout. It wore well for eight hours before fading visibly.
