Quick Answer
Choose the Flex Reusable Disc if you want one purchase that lasts for years and replaces hundreds of disposables, and you are comfortable with a short cleaning routine. Choose the Flex Disc if you prefer the convenience of a disposable disc you can toss after use, especially for travel, unpredictable schedules, or a lower upfront cost. Both provide up to 12 hours of leak protection, so the real decision is between ongoing convenience and long-term value.
Cost Per Cycle: How the Numbers Compare
The Flex Reusable Disc costs USD 24.84 (catalog comparison price USD 34.99) and lasts for years, replacing hundreds of disposable discs. The Flex Disc costs USD 11.38 per pack (catalog comparison price USD 16.49), with quantity options available. If you use one disc per cycle, the disposable option may cost less at first, but the reusable disc typically pays for itself within a few cycles. Your actual cost per cycle depends on how many discs you use and how often you replace them. For a detailed breakdown, see the Flex Disc cost per cycle in the product details.
Capacity and Protection: What Each Disc Holds
The Flex Reusable Disc holds the equivalent of 6+ super tampons, while the Flex Disc holds the equivalent of 5+ super tampons. Both are designed for up to 12 hours of leak protection, including heavy flow and overnight wear. If your flow is very heavy, the reusable disc's slightly higher capacity may mean fewer changes. However, both are effective for most flow levels, so capacity alone may not be the deciding factor.
Material and Waste: Silicone vs Disposable
The Flex Reusable Disc is made from 100% medical-grade silicone, is hypoallergenic, and is designed to reduce cramps. It produces no ongoing waste beyond packaging. The Flex Disc is a disposable menstrual disc; it is not reusable, so each use generates waste. If reducing environmental impact is a priority, the reusable disc is the clearer choice. For a plant-based disposable option, consider the Flex Plant+ Disc, which produces 71% less waste than traditional pads and tampons.

Fit and Comfort: What to Expect
Both discs sit in the vaginal fornix rather than pressing against the canal, which is why most people experience fewer cramps, no odor, and no disruption to vaginal pH. The Flex Reusable Disc has a patented notch that makes folding and insertion easier. The Flex Disc is inserted similarly but is disposed after use. Neither product record includes specific sizing dimensions, so if you are unsure about fit, start with the disposable disc to test the shape before committing to the reusable version.
Trade-Offs at a Glance
- Upfront Cost vs Long-Term Savings: Flex Reusable Disc costs USD 24.84 and lasts for years; Flex Disc costs USD 11.38 per pack and is disposable. The reusable disc typically pays for itself within a few cycles, but the disposable disc requires less commitment upfront. If you plan to use discs for more than a few cycles, the reusable disc is more economical.
- Convenience vs Maintenance: Flex Disc can be tossed after use, making it ideal for travel or busy days. Flex Reusable Disc must be cleaned and stored between uses, adding a small routine. Choose disposable if you value zero cleanup; choose reusable if you don't mind a quick wash.
- Waste vs Capacity: Flex Reusable Disc holds 6+ super tampons and produces no ongoing waste. Flex Disc holds 5+ super tampons and generates waste with each use. For heavy flow and lower waste, the reusable disc has a slight edge; for lighter flow or occasional use, disposable is sufficient.
