    How Do I Use the Casco Cup?

    Congratulations on making the choice to switch to sustainable and comfortable period protection. We know that using a Casco Cup can seem intimidating at first, that's why we wrote the official guide on how to use a menstrual cup.

    We strongly encourage anyone new to Casco Cup to read through our guide. Beyond that, here are a few pointers:

    • Make sure to clean your cup in boiling water at least once during your cycle and once at the end, in addition to rinsing it between uses whenever possible.
    • When inserting or removing your Casco Cup, make sure your hands are clean and relax your muscles.
    • After inserting the Casco Cup, gently move your fingers around it to make sure it has regained its circular shape. This will prevent leaks. If it hasn't, gently twist it several times or reinsert it.
    • When removing it, squat over a toilet or in the shower and push your muscles as if you're having a bowel movement. This will help move the cup downward.

    Can I Use the Casco Cup?

    We are not doctors, so we cannot give you medical advice. We strongly encourage anyone with a question about their health to speak with their gynecologist. See our FAQ for more answers to commonly-asked questions on who can and cannot use the Casco Cup.

    Excellent product!

    Great product! Easy to use.

    Great customer service

    I contacted Casco when their smallest size, which I ordered, was still too large for me. They promptly gave me a refund. Great customer service!

    The right size matters!

    Ive previously tried two cups from a very popular brand. While the products were great, the size was not right. So after getting a better idea of the length and diameter I needed, I choose casco. My first experience with casco was nearly perfect! Nearly because im still going through a learning curve. I wish the customer service responded because I had a question. Its been weeks now.

    Works great!

    I first tried another brand of cup and found out I have a high cervix, cue the research that led me to the Casco Cup. This cup has resolved my previous issues and im happy with my purchase.
