Thank you for viewing. I am clearing out my parents' house. These are materials for stained glass that my mother used to learn. Many of them have glass number stickers attached, and there are cutter marks and scratches. I am an amateur and cannot answer questions about the glass. The items will be wrapped in bubble wrap for shipping, but they may break during transit. Also, it may take some time to ship. Thank you for your understanding and I hope someone who can make good use of them will purchase them.
