Every item can be returned for refund within 2 weeks (this time period begins at date of arrival at your home), as long as it is unused and undamaged and in original condition. If you want to return a painting, it is up to you to make sure it gets back to me safely in its original condition AND in time. 
In any case, please feel free to contact me if questions occur.
