Aw, sorry that it didn't meet your expectation. I only have one current MAC polish - Mean and Green. I really liked the duochrome but was worried I'd be unhappy with it. Luckily it seems to be one of their better formulas.
I do have one other ancient MAC polish - Chili.
It's in a short, square bottle with a tall skinny wand top. It must be about 10 years old, but it hasn't gotten thick or gloopy. I don't think I've used it in at least 7-8 years. I'm just keeping it now because I figure the bottle is almost a museum piece. I almost turn it in each BTM but always pull it out at the last minute.
