All orders sent 2nd class. Please enquire if you need your feminism faster than that!


When will I get my order?

All your orders are posted out the next day (or the same day, if they are placed in the morning).

Because of the Covid-19 crisis, the post is taking a bit longer than usual. If you're in a rush, drop us a line and we'll see what we can do.

Massive gratitude to the Royal Mail right now for powering through.


Do you take commissions?

We do take commissions for illustrations and have produced work for a number of organizations including Kensington Palace.

Where does the name Clavis & Claustra come from?

Clavis & Claustra is Latin for ‘key and lock’. Ornate antique keys are beautiful, aren’t they? They make you think of secret passages, buried treasure and adventure. But in this case the secrets are stories of pioneering women. And the buried treasures are their incredible lives and achievements. Liberate them and you might be inspired to change the world too. You have the key. It’s your adventure.
