These zippers are a great novelty item and are made by Stephanoise of France, who make a lot of zips, braids, tapes and other sewing accessories.
The zippers are 40cm (16in) long. When the zipper is closed the tapes and teeth measure 2.5cm (1in) from edge to edge. When closed, the teeth measure 3mm (1/8in) across. The teeth are plastic as is the slider pull, but the slider itself is made of metal. The diamantes are embedded in the teeth and the slider pull.
The colour of the teeth, slider and bottom stop are the same as the colour of the tape. However, the rhinestones/diamantes are colours which complement the tape and teeth and this makes give the whole zip a fascinating "twinkle".
The zipper is able to open at the top only as the bottom stop is not moveable. However the zip can be shortened, if needed, by putting some stitches of strong thread around the teeth at the required length and then the excess can be carefully removed with a craft knife or a sharp pair of scissors. The end of the shortened zip can be hidden by hiding it under the fabric.
The zipper can be inserted into garments so that the diamantes and teeth show but none of the tape is visible to make a stunning feature zip on evening dresses or other garments. The zipper could also be a statement feature on the outside of garments or other projects as the diamantes embedded in the teeth make an appealing bit of bling even though only a small part of the zip is visible.
The zip is machine-washable, although hand-washing would be better!
