Various types of glass pieces in similar colors are included. How about giving them a try? All have a coefficient of expansion of 96. These are larger glass pieces than the sample color scraps sold separately. If you prefer smaller pieces, I can cut them for an additional 100 yen, so please comment before purchasing. The types are unknown, so please check the images. Please note that there may be magic marker writing or tape residue. Approximately 100 grams in total. Please use them for making small items. I will pack them carefully, but there may be breakage during transportation. Please also note that I will use recycled materials such as newspapers and cardboard for packaging. I will pack the items upon completion of payment, so I cannot accept requests for combined shipping or changes after that. Shipping will be via Click Post if the package is within 1 kg, and Yu-Packet Post if it's within 2 kg, including packaging materials. There is no combined shipping discount for items under 500 yen.
