I have cut scrap stained glass into pieces approximately 2x2 cm (inside/outside). How about giving them a try? 30 pieces Same color family, with duplicates. 4-5 types Please use them for making small items. Please note that they are not perfectly square! Shipped via Click Post. I will pack them carefully, but there is a possibility of breakage during transportation. Especially when purchasing multiple sets, they will be packed together, making them more prone to breakage. There is no guarantee for breakage. If you wish to have them shipped as fragile items, we will change to Takkyubin (home delivery service) and add shipping costs, so please contact us before purchasing. Please note that we will use recycled materials such as newspapers and cardboard for packaging. We will pack the items upon payment completion, so we cannot accept requests for combined shipping or changes afterward. The maximum for combined shipping is 3 pieces (or 4 pieces if they are small) per package. We will offer a discount from the second package onwards. We have set the shipping time to 4-6 days, but we will ship as soon as they are ready. If the weight including packaging is within 1 kg, we will ship via Click Post; if it is within 2 kg, we will ship via Yu-Packet Post.
