In the early days of BoxMac, we used Custom Ink as our clothing provider, and have since moved to TeePublic since 2017. However, we sometimes get requests for the hats and sweatshirts (though unfortunately, the original BoxMac yellow baseball shirts are no longer available on Custom Ink!). These clothes require purchasing minimums, so to get one would require a lot of friends, but JUST IN CASE you’re interested, you can still get them at exorbitant prices at these links:
