Durex - AIR Extra Smooth Condom (HK Edition) 10 Pcs

Please refer to the following figure for the condom size dimension calculation

Nominal width is the measurement of condom when it is flattened. Therefore nominal width is half of the circumference (perimeter). Please also note that condoms are made of elastic materials, therefore exact size is not recommended. Instead, a smaller condom should be used to prevent slipping off. Try different size and see which one fit you most comfortably.
