Your custom advertising or business flags are designed for both indoor and outdoor use and can get wet and be used in the rain. They can then be air dried or even washed as needed afterwards. Please see the product pages for specific washing instructions if this is needed. However, use during rain or other weather may impact the lifespan of your flag. Although flags are suited for both indoor and outdoor use, when heavy or severe weather occurs, we recommend you take them down and store them until the weather clears. Failing to do so can result in permanent and irreparable damage to your flag and or pole set.
