I have cut scrap stained glass into pieces approximately 2x2 cm (inside and outside). How about giving them a try? 30 pieces There may be duplicates. (I try not to include too many 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 breakage. There is no guarantee for breakage. If you wish to have them shipped as fragile items, we will change the shipping method 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 after that. The limit for combined shipping is 3 pieces (or 4 if they are small) per package. Discounts will be applied 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 package weighs less than 1 kg including packaging materials, we will ship via Click Post; if it weighs less than 2 kg, we will ship via Yu-packet Post.
