Does the MCUK hold more than a tampon?
The MCUK menstrual cup holds 3 times more liquid than a regular tampon.*
The size A MCUK can hold 29.3 millilitres, and the size B MCUK can hold 28.8 millilitres to the rim.
However, you will still need to empty your menstrual cup every 4 to 8 hours, depending on your menstrual flow, and always after a night’s sleep.
*Tampons can hold anything from 6 to 18 millilitres depending on the absorbency you choose (Regular to Super Plus Extra).
