This contains various types of glass pieces. Would you like to try them? All have a coefficient of expansion of 96. These are larger glass pieces than the sample color scraps also on sale. If you prefer smaller pieces, I can cut them for an additional 100 yen, so please comment before purchasing. I do not know the specific types, 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 shipping. Also, I will use recycled materials such as newspapers and cardboard for packaging, so please understand. 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 within 2 kg, including packaging materials. There is no combined shipping discount for items under 500 yen.
