📢 📢 📢 Just an update on the tee debacle:

We sincerely apologize for how long this process has taken. Due to the issues with the original tee drop, we ultimately had to switch print shops and restart the entire process.

The good news is that the new shirts will be much higher quality and should turn out SO much better. The new shop was kind enough to fit our large order into an already booked schedule and the blank shirts were dropped off earlier this week.

We do not have a definite completion date yet but they should be finished fairly soon.

If you preordered in April or May and received one of the original defective prints, your replacement will be the first to ship (free of charge) as soon as the new shirts are in our hands. We seriously appreciate your patience throughout this entire ordeal.

If you ordered in late June or earlier this month after the preorder reopened, your order will ship immediately after, within the following days.

Thank you again for sticking with us while we worked to get this corrected and done properly so this never happens again.
