Whether you’ve never made a Corsi-Rosenthal Box (aka CR box), or you’re a pro and just need to replace your existing filters, feel free to join us in the shop!

Feel free to bring your own supplies, or purchase them from our shop. This social event will have some supplies free and open for everyone to use, and CR boxes will be set up to help maintain a safe environment. Wearing a mask is recommended, and will be supplied if you don’t bring one with you.
