omg! what great news! ok i completely agree with you in that i need it...but will i need a backup???
i think paintpots are a great deal...even though there's a ton of product in one pot (if i could quantify, i would say well over 600 applications in one pot), i think it's pretty easy to use a paintpot up to the point where I can justify getting a couple (and i am TERRIBLE at using things up, I have been using the same select moisturcover for 3.5 years now)...and I have small asian lids.
As far as expiration goes, i have had 4 since the original painterly August 2007 release, and the rest 8 from the first mac FF sale in 2008 (plus some fafi ones)...with the exception of blackground, which has moved away from the pot's edges quite a bit, all the other ones look quite alright...so 3.5 years and they're still going strong..
my only concern is that frosty paintpots are better used during incandescant lighting i think...they can be too much for day wear and may reflect different sources of light weird...that's not going to stop me from getting all 4 though....
so if anyone needed to be enabled, there's my schpiel on how great paintpots are...not that anyone needed any more enablling!
