COVID-19 UPDATE:
Painless is dedicated to providing high quality products to our customers while keeping our employees safe during this COVID-19 pandemic. To maintain employee safety, all employees able to work from home are doing so. Our production staff has been split into smaller groups, allowing us to keep producing the high quality products you expect safely, but at a slower rate. During this time you may experience some slight delays reaching us due to a limited staff and high call volume. Please bear with us as we work through this uncertain time.
