Since these are hand crafted products, the exact color of glass pieces may vary. Colors of the glass will appear darker and less vibrant when not illuminated. Handmade glass will vary from one piece to the other; glass made at different times will also vary. Use the size under product specifications to determine the product size. Again, since these are hand crafted products, dimensions for all glass window panels and fireplace screens may vary from 1/4 to 1/2 inch. Stained glass product has been protected with mineral oil as part of the finishing process. Please use a soft dry cloth to remove any excess oil.
