Changed font for product price using custom css, but when selecting product option, font reverts

I added the following css to make the prices on my product pages in my desired font (BN Tillsdale).

.sqs-money-native {
    font-family: 'BNTillsdale';
}

However I noticed when I select a production option from a drop down menu, the price reverts back to the original font. Example URL: https://www.minerbook.co/shop/p/build-your-own-writing-journal-large If you select a "cover style" the price will revert.

Is there a way to fix this so the price uses the BN Tillsdale font regardless of the option chosen?

@paul2009 That worked, thank you!
