Welcome the latest edition to the family! This is MAC's Pro Longwear Paint Pot in 'Vintage Selection' ($18.50). The only other Paint Pot that I have is in Painterly, and I mostly use it as a base so less pigmented shadows have something to adhere to once I apply it over my lid. Paint Pots help eyeshadows from creasing, at least on my lid. My lids are not especially oily, nor is creasing a big issue that I have, but it's always better to be safe than sorry when you don't have all of your make-up within reach to fix or touch up.
