How To Use

New here? You've got this.

It might look intimidating at first, but trust us — switching takes one cycle to learn and zero to regret. Here's everything, step by step.

The Muses Cup — the basics.

Step 1

Wash up

Clean hands before every contact with the cup — always. It's the one rule with no exceptions.

Step 2

Fold it

Press the cup flat and fold in half — the C-fold. Or push one edge down into the cup — the punch-down. Use whichever feels easier.

Step 3

Insert & let it open

Relax. Insert at a slight angle toward your tailbone — not straight up. You may feel a soft pop as it opens and seals.

Step 4

Forget it for 12h

Swim, sleep, train, live. If it's in right you won't feel it. On heavy days, check every 4–6 hours while you learn your flow.

Step 5

Remove gently

Bear down, pinch the base — not the stem — to break the seal, and ease it out. Empty into the toilet, rinse, reinsert.

Sterilising the cup in a pot with a whisk

Step 6

Boil between cycles

Sterilise in boiling water — 3 minutes before your first use, 5–10 at the end of each period. Tip: rest the cup inside a whisk so it doesn't stick to the pot.

The Muses Panties — even easier.

Wear them exactly like regular underwear — solo on lighter days, or as backup with your cup on heavy ones. Then:

1 · Rinse coldStraight after wearing, until the water runs clear. Cold — hot water sets stains.

2 · Wash at 30°Gentle cycle, in the mesh laundry bag from your kit.

3 · Skip the extrasNo softener, no bleach, no tumble dryer, no iron.

4 · Air dry flatThat's it. With care, they stay absorbent for years.

Still got questions?

What if I can't get it in on the first try?

Completely normal — most people need a cycle or two of practice. Try a different fold, a different position (one leg up works for many), and above all: relax. Tension makes insertion harder. It gets dramatically easier, we promise.

How do I know it's sealed properly?

After inserting, rotate the cup gently once or run a finger around the base — it should feel round and open, not folded. A good seal means no leaks for up to 12 hours.

Can it get lost inside me?

No. It physically cannot go anywhere — the vaginal canal ends at the cervix. If it rides up, relax, bear down gently, and pinch the base to bring it out.

Can I use the toilet with it in?

Yes — the cup sits in a different canal. Carry on as normal.

Is it safe to wear overnight?

Yes — up to 12 hours, which covers even the longest lie-in. Empty it before bed and when you wake up. Never wear it longer than 12 hours; if you ever experience sudden high fever, vomiting, rash or dizziness while using it, remove it and seek medical help immediately.
