These are luxurious lace motifs, like those used on wedding dresses. The white lace is corded lace, with pearls carefully sewn on one by one. The black one is a three-dimensional motif lace, and sequins sparkle on the surrounding leaves. They are used by cutting them off individually. Enjoy them by sewing them onto hats or bags, or using them for brooches, depending on your ideas. Purchased in Korea.
