Each stained glass is approximately 9.5"x9" and made from glass, copper foil and leading.
When hanging your glass ONLY use commerical grade suction cups. trust me others just won't work. or a good ole hammer and nail above the window frame can work as well. Lordyhoardy is not liable for any breakage after shipping.
When caring for your glass the best practice is to buff it out with some wax for that gorgeous shine, however a light wipe down using warm water and soap works just fine
