WTF is a
Period Cup?

A new, reusable, sustainable alternative to tampons.

Why Make The Switch?

  • Vagina Friendly

    Unlike tampons and pads, the cup collects your flow instead of absorbing it, so you can say goodbye to irritation and dryness.

  • Earth Friendly

    Disposable period products go straight to the landfill while our period cup can be used over and over and over again.

  • Wallet Friendly

    This is a one-and-done type of deal. Switching to the period cup will save you money (and late night drug store runs) over time.

How It Works?

Much easier than you think.

  • 1 Fold to insert.

    Fold the cup into a U shape, then gently insert into your vagina. When you let go, the cup will position itself at the base of your vagina, creating a super secure, leak-proof seal.

  • 2 Wear.

    It’s completely safe to use while exercising, traveling, and sleeping for up to 6 hours.

  • 3 Empty.

    After washing your hands, pinch the base of the cup to break the leak-proof seal, gently pull at the base, and empty it into the toilet.

  • 4 Clean.

    Use warm water and gentle soap to clean the cup before each use. To disinfect, place the cup in its carrying case, fill with water, and pop it in the microwave with the lid open for 5 minutes. Good as new!

How sizing works

Two-sizes fit all.

  • Size One.

    For young people, athletic types, and those of us with lighter flows.

  • Size two.

    For those of us who've given birth vaginally or have heavier flows.

No Risk. All Reward.

Nervous? Don't be! We've made it super low-pressure on you.

  • Free Shipping.

    Get the cup delivered straight to your door with no extra fees.

    We'll give you a free box of 100% organic cotton liners to use while you adjust to using the cup.

  • Money Back Promise.

    If the cup isn’t your thing, no worries—we’ll give you a full refund.

Still have questions?

Here are some FAQs but feel free to reach out to us anytime here.

  • Does it hurt to insert a Sustain Period Cup?

    Inserting the cup should be painless! Check out our quick video for some guidance. And if you suffer from vaginal dryness we recommend you moisten your cup with a little water or Sustain’s personal lubricant.

  • How long can I wear my Sustain Period Cup?

    We recommend wearing it for 6 hours at a time. Remove your cup, clean it (with water and a gentle soap) and then you can reinsert it for another 6 hours. If you are on the go, you can use a second cup to save cleaning and disinfecting for a convenient time at home.

  • What’s the stem all about?

    The stem is designed for first-time cup users to guide insertion and removal. Once comfortable with your cup, feel free to trim the stem with scissors to a length that feels most comfortable (the stem shouldn’t protrude from your vagina).

  • How long will my cup last?

    Your reusable cup will be good for up to 3 years. Please be sure to follow all proper use and care instructions to retain integrity.

  • Can I have sex while wearing my cup?

    Nope! Make sure to remove your cup before having fun!
