Compare Flex Cup and Flex Reusable Disc cases for storage and travel. See which fits your on-the-go period care needs and lifestyle.

Quick answer

If you primarily use a reusable disc, the Flex Reusable Disc case offers a tailored, protective storage solution for your disc. If you're a cup user, the Flex Cup case is designed to fit your cup and its pull-tab, making it the better choice for your specific product. Both cases are compact and travel-friendly, but the right one depends on which period product you use most.

When you invest in a reusable period product like the Flex Cup or Flex Reusable Disc, protecting it between cycles is key. A dedicated case keeps your product clean, safe, and ready to go—whether you're storing it at home or tossing it in a bag for travel. But with two distinct cases available, it's worth comparing how each fits its respective product and what that means for your routine.

This comparison focuses on storage and travel. We'll look at the Flex Cup case and the Flex Reusable Disc case, how they match their products, and what trade-offs to consider before you pick one.

Why a dedicated case matters for your reusable period product

Reusable period products are an investment, and a case is the first line of defense against damage, dirt, and bacteria. The Flex Cup is made from medical-grade silicone and features a patented pull-tab for easy removal. A case that accommodates that tab prevents it from getting bent or snagged. Similarly, the Flex Reusable Disc is also made from 100% medical-grade silicone, and its flexible rim needs protection from being crushed or deformed in a bag.

A dedicated case also keeps your product separate from other items in your purse or backpack, reducing the risk of contamination. It's a simple way to maintain hygiene between uses, especially when you're on the go and don't have immediate access to a sink.

  • Store your reusable product in its case when not in use to keep it clean and safe.
  • For travel, a case prevents your cup or disc from being squished in luggage.

Flex Cup Case: tailored for cup users

The Flex Cup case is designed specifically for the Flex Cup. Because the Flex Cup is the only cup with an adjustable, patented pull-tab, the case is shaped to accommodate that feature. This means your cup stays in its intended shape, and the pull-tab remains accessible and undamaged. The case is compact, making it easy to slip into a purse, backpack, or even a pocket.

If you're new to cups, the pull-tab is a game-changer, and the case ensures that this unique feature is protected. It's a practical choice for anyone who wants a dedicated home for their cup and values easy removal during their period.

  • The Flex Cup case is designed to fit the cup's pull-tab, keeping it in perfect condition.

Flex Reusable Disc Case: built for disc storage

The Flex Reusable Disc case is designed to hold the Flex Reusable Disc, which is modeled after the best-selling disposable Flex Disc. The disc's flexible rim needs a case that won't distort it, and this case provides that protection. It's also compact and travel-friendly, so you can carry your disc discreetly.

For disc users, this case is the obvious choice because it's made to fit the disc's shape. It keeps the disc clean and ready for up to 12 hours of wear, whether you're at home or on a trip.

  • The Flex Reusable Disc case protects the disc's rim from bending or damage.

Trade-offs to consider

  • Case compatibility: The Flex Cup case is tailored for the Flex Cup's pull-tab, while the Flex Reusable Disc case is shaped for the disc. Using the wrong case might not offer a secure fit. Choose the case that matches your primary product.
  • Travel convenience: Both cases are compact and travel-friendly, but the Flex Cup case might be slightly smaller due to the cup's size. The disc case is also discreet, but the cup case could be easier to slip into a small bag. Consider your typical bag size when choosing.
  • Protection level: Both cases offer dedicated protection, but the disc case is designed to prevent rim distortion, which is critical for the disc's performance. The cup case protects the pull-tab, which is essential for easy removal. Think about which part of your product is most vulnerable.

Product facts at a glance

  • Flex Cup: Flex Cup is a reusable menstrual cup made from body-safe, medical-grade silicone, and the only cup with an adjustable, patented pull-tab that makes removal as easy as a tampon. The pull-tab is a unique feature that needs a case designed to accommodate it, which is exactly what the Flex Cup case does.
  • Flex Reusable Disc: Flex Reusable Disc is a reusable menstrual disc modeled after our best-selling disposable Flex Disc. Made from 100% medical-grade silicone, it provides up to 12 hours of leak protection and holds the equivalent of 6+ super tampons. The disc's flexible rim requires a case that won't distort it, and the Flex Reusable Disc case is built for that purpose.

Which case fits you?

Best for

  • Flex Cup users who want a case that accommodates the pull-tab and keeps it safe.
  • Travelers who need a compact case that fits easily in a purse or backpack.

Not for

  • Flex Reusable Disc users who need a case designed to protect the disc's flexible rim.

Both the Flex Cup case and the Flex Reusable Disc case are smart investments for protecting your reusable period product. The right choice comes down to which product you use. If you're a cup user, the Flex Cup case is your match; if you're a disc user, the Flex Reusable Disc case is the way to go. Either way, you'll keep your product clean, safe, and travel-ready.
