Bicchiere Mug - Set of 4 - 6 Colors

Looking for the capacity of these mugs - found this: http://www.amazon.com/Guzzini-Bicchieri-Feeling-White-22390165/dp/B000VRTUCQ

!!! - but still dont know the capacity

This Site in Italian lists it at 250cc which a google query says is just over 8 oz. So smallish for my American appetites!

9.3oz
