Industry quality nylon hook and eye closures. There are hooks and eyes spaced every 3/4" and the eyes have three columns for adjustability. The tape can be trimmed to fit and needs no finishing, but we prefer to zig-zag along the cut edge to finish it off. Sold by the full or part metre. There are 53 hooks and eyes to a metre (40"). A bustier or long-line bra will typically use .3 metres. (12")
