Spiral steel bones are the most flexible bones and enhance curves. They're flexibility makes them a great choice for dancewear but they are not a good choice if you need a lot of support.
Spiral bones are made of steel, looking as if a fine coil of steel has been flattened. Spiral steel bones are available in three sizes, 3/16" (4mm), 1/4" (7mm) and 7/16"(10mm). The 1/4" comes either by the metre or in pre-tipped lengths (both in galvanized wire) and the 7/16" is sold by the metre in a grey galvanized colour and by the piece with a shiney zinc coating.Spiral bones have the most flexibility of all bones, being able to move both forwards and backwards and side to side. They are the best choice for a bodice that requires boning but is going to be worn for dance or other motion activities. They are not a good choice for front panels of bodices/corsets for women who wear a c-cup or more, unless you are using the 7/16" size. Spiral bones are the most flexible and least supportive. Bodices with these can be dry cleaned but not laundered with water.


You need to order full meters of this product when it is sold by the meter. The system does not accept anything like 9.5 so round the amount you need up to the next full meter.

Note: 1 meter is 3 inches longer than 1 yard
