Set of two 800m GOLD TIRE sewing threads, color numbers 51 and 56. - Brand: GOLD TIRE - Colors: Light gray-blue (color number 51), dark greenish-blue, teal (color number 56) - Length: 800m - Type: Sewing thread Thank you for viewing. I believe these are unused items that have been stored for a long time. Please understand that there may be scratches and dirt on the film and bobbins. These are not current color numbers. Color No. 751 and No. 756 seem similar, but No. 51 appears a bit more silver-like, perhaps due to its sheen. This is a long length, equivalent to about 6-8 spools for home use, similar to commercial use. Will be shipped in simple packaging. Although stored in a separate room, there are a cat and a smoker. Thank you for your understanding.
