A Note About the Covid-19 Situation:

As all small businesses are affected by the Covid-19 pandemic, so are we. Supply chain issues, coupled with extended transit times has slowed down our production. Although we try to keep production levels consistent, expect a few delays with your order. Most issues we are seeing are due to a slower delivery period with the USPS. We send out tracking numbers when the package is expected to hit the Post Office, but sometimes those tracking numbers aren't active for a few days.
