Thank you for viewing. I'm clearing out my parents' house. These are materials for stained glass that my mother used to learn. Size: Glass scraps, approximately 7.5 x 4 cm, 50 pieces I haven't checked each piece carefully, so there may be scratches or dirt. Glass number stickers are attached, but they may be difficult to remove due to long-term home storage. I am an amateur, so I cannot answer questions about the glass. Shipping is planned via Yu-Packet Plus. There is a possibility of breakage during shipping. It may also take some time to ship. Thank you for your understanding. I hope someone who can make good use of these will purchase them.
