I've cut scrap stained glass pieces to approximately 5x5 cm (inside/outside). How about giving them a try? Includes pieces from sheet glass brands like Uroboros, Bullseye, Kokomo, and Spectrum. The contents vary depending on the stock at the time, so please check the images. I don't know the specifics of each individual glass piece. 20 pieces Please use them for making small items. They are not perfectly square. If you need precise sizes, please refrain from purchasing, as the shapes vary. I've set the shipping time to 4-6 days, but I'll ship as soon as they're ready. Shipping will be 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 stacked and packed, making them more prone to breakage. There is no guarantee for breakage. If you prefer fragile handling, I will change the shipping to Takkyubin (home delivery service) and add shipping costs, so please contact me before purchasing. Please note that I will use recycled materials such as newspapers and cardboard for packaging. I will pack the items upon payment completion, so I cannot accept requests for combined shipping or changes after that. For combined purchases, the limit is 3 pieces (or 4 if they are small) per package. Discounts will be applied from the second package onwards.
