700m gray silk sewing thread, #50, Earth Bell, Kinrei brand. - Color: Gray-based gunmetal - Length: 700m (when new) - Material: 100% silk - Brand: Kinrei Earth Bell Kanagawa - Thickness: #50, for general fabrics - Color number: 72 Thank you for viewing. This is a used silk sewing thread. It's a dark gray color with a sheen, appearing like dark silver or gunmetal. It's a large spool, several times the size of a 100-130m home bobbin, so there's plenty remaining. I hope you can find a use for it. It will be shipped in simple packaging. It's stored in a separate room, but there are cats and a smoker in the house. Thank you.
