Curve Menstrual Cup
The Curve Menstrual Cup features a smooth, ergonomic design that contours to your body for comfortable, leak-free period protection. This reusable menstrual cup can be worn while exercising, swimming and sleeping, day or night, for up to 12 hours before being emptied and cleaned.
The unique curved shape may be more suitable for those with a sensitive bladder who find classic bell-shaped menstrual cups uncomfortable. The tilted rim can also be helpful for individuals with a tilted cervix or uterus, allowing them to create a better seal and help prevent leaks.
Sizes & Specifications
Choosing the right menstrual cup involves more than selecting Small or Large. Your cervix height, cup diameter, total length, menstrual flow and personal comfort preferences can all influence which size may suit you.
The Curve is available in two sizes, with different dimensions and capacities.
| Specification | Small | Large |
| Diameter | 45 mm | 48 mm |
| Total Length, including stem | 58 mm | 68 mm |
| Cup body length | 40 mm | 49 mm |
| Stem length | 18 mm | 19mm |
| Capacity to suction holes | 25 ml | 30 ml |

Small
The Small Curve has a 45 mm diameter, a total length of 58 mm and a capacity of 25 ml to the suction holes.
Its shorter overall length may be worth considering if you have a lower-to-average cervix, provided the diameter and capacity suit your needs.
If you have a heavier menstrual flow, you may need to empty this size more frequently.
Large
The Large Curve has a 48 mm diameter, a total length of 68 mm and a capacity of 30 ml to the suction holes.
Its greater length and slightly wider diameter may suit someone who prefers a larger cup or needs additional capacity.
The increased capacity may allow longer intervals between emptying compared with the Small, depending on your menstrual flow.
Remember: A larger cup is not automatically a better fit. Consider your cervix height, available space and comfort when choosing between the two sizes.
Not sure which menstrual cup size, shape or firmness may suit you? Choosing the right cup involves considering your cervix height, flow, anatomy and personal preferences.
