ONLY PIECE: Vintage? Modern? Glass? Silver Beaded Trim on Nylon 10mm x 1.8m

Item: this trim has been cut from a garment, by the looks of it. I am also selling matching beaded embellishments. I think they are glass beads going by the weight and it is on clear nylon backing.
Width: the beads are 10mm plus 8mm of nylon either side
Condition: cut from a garment, I think. Great condition. The beads are separated where the nylon ends - there are two areas like this - however, when flat they look joined.
Purchase Size: we can't cut this piece without resewing beads, so we're selling the piece as removed from the garment. It is 1.8m long.

We are not haberdashery experts, but we're eager learners and doing out very best to accurately describe these pieces.  We sell our trims and laces by the 1/2m to cater for crafters who only need smaller pieces, but multiple quantities purchased are sent uncut (unless specified otherwise). Please note most of our trims and laces are old. We check all items before listing them and will list any faults above. However, sometimes small spots get through our eager eyes, so please keep the age of this product in mind when purchasing. If you have any further questions please don't hesitate to contact us.
