Discs
Four discs, 45–50ml — more capacity than the largest cup in the range (40ml). A disc sits behind the pubic bone rather than sealing on suction, which is a different learning curve from a cup.

Disc vs cup
A disc stays put by position, not suction. No vacuum to break on removal, and no suction feeling while worn.
Capacity
45–50ml — one step above the largest cup in the range (A09, 40ml).
Selection note
Cervix height sets the disc diameter, and the logic is the reverse of cup sizing: a low cervix can rule out a deep disc.
