24 Pieces 13.7 Inch Metal Steel Corset Boning Spiral Boning Precut with 24 Steel Boning Tips Structure and Form for Sewing Corset, Costume, Collar, Cuff and More (6mm)

The media could not be loaded. I had tro buy all three because i just didn't know which would work better for my purposes, but if this helps, the picture shows a 1/4" steel boning, a 1/2" steel boning, and the 6mm spiral boning on the paper with some visual references on the side in the form of some coins so you can get a better understanding of just how big they are in real life. and then the video shows how flexible these are and what they look like.These work fantastic for boning corsets. They allow you to be more flexible and serves for a much natural looking figure. The only thing I did learn though is that next time I will get a roll of the spiral boning and the end caps because I needed various sizes, but had to make do with the one sizer fits all given here. That is my fault though, so I can't take a way a star.Also, delivery was incredibly fast.
