Thank you for your question, this brick is a slim brick that we sourced from Mutual Materials (Bellevue/WA location) - we mixed a few different types together to create the old, mismatched look. We used a combination of 'Mutual Used' and 'Ashland Used'. The trick to creating this old-world look was the installation - slim brick is installed like a tile, so we requested that they be set somewhat uneven and imperfect, and we used mortar instead of thin-set.

Thank you!
