Beware of similar looking pictures and randomly assigned reviews on Amazon. There are genuine reviews out there - it's just that the 'Amazon computer' puts them against different products to the ones the reviewer intended. So, these are not the 'big manly mugs'. They are normal size, quite well made, measuring: 86mm height, 71mm opening and nearer 6oz than 10oz. If we are going to use gender stereotypes: they are best described as 'unisex'.
The big, hairy, manly, tough, heavy, etc. ones are about 102mm in height and 77mm across the opening. Now that is a man's (or a woman's) cuppa!
