Lacy-looking elastic with a clear nylon thread running along the length, where it is meant to be to be folded over to enclose and finish raw edges at the waist and leg opening of undies, safety shorts, top edges of bralette cups, etc. I think it could also be used flat/ not folded over, if you like. These are thin - less than 1mm thick. Typically used in making inner wear, not suitable for other applications. To preserve the life of anything with elastic, avoid washing at high temperatures or tumble drying.
Pale apricot is a pretty good match to the Light apricot 13mm lingerie elastic also available in the shop.
