Can't change the product titles into a custom font

Hi community,

I'm using a custom font and I've been able to change the h1,h2,.. styles into the correct font with CSS...but I can't do the same for the product titles.

I need urgent help. 

Thanks in advance!!

.ProductItem-additional is RELATED PRODUCTS.

Try with

.product-title

if it doesn't word, please share link to your site to check code

Thanks for your message. It's not working at the moment. I'll send the site when it's online. Should be tonight. 

Before that,...any other ideas?

Hi there. Same problem over here. Tried using .product-title but did not work.

h1, 2, 3, and p are working fine with custom fonts. Any ideas?

here's a link to the product page. 

Just solved it. In case anyone has the same issue:

.tweak-product-item-details-show-title .ProductItem-details h1.ProductItem-details-title {
  font-family: 'FONT NAME';
}
