Keeper Moon Cup Capacity?

Since we've discovered a discrepancy in the capacity numbers for Mia today, it seemed a good time to ask if anyone can verify the capacity for the Keeper Moon Cup.

I'm especially interested in the large one. According to the size chart, its width is similar to other small cups at 44, and it holds about 15ml.

I have been considering trying this cup, because it's the only one I know of without grip lines/rings--I really don't care for them. :) But 15ml wouldn't be an improvement over my sm Yuuki.

Thanks for any help.
