I have cut scrap stained glass into pieces approximately 2x2 cm (inside and outside). How about giving them a try? 30 pieces Similar colors, with duplicates. Please use them for making small items. Please note that they are not perfectly square! Shipping via Click Post. I will pack them carefully, but there is a possibility of breakage during shipping. Especially when purchasing multiple sets, they will be packed together, making them more prone to breaking. 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. Please contact me before purchasing. Please note that recycled materials such as newspapers and cardboard will be used 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. Discounts will be applied from the second package onwards. Shipping is set for 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 within 2 kg, we will ship via Yu-Packet Post.
