Modern? Vintage? Coat Button Black Rope No Shank Large 45mm Wide

Size: 45mm wide
Material: I have no idea whether this is a modern or vintage button. It feels like a twine or a fine rope and is the same pattern both sides - no shank or sew holes. It looks like the centre is a metal disc as I can see some shine through the twine.
Hole or Shank: neither - it can be sewn on using the twine as leverage
Raised or Flat Face: slightly domed both sides - at the thickest point in the centre it is 1cm
Condition: good condition - a couple of strands have moved, but nothing untoward.
Number of buttons: we have two buttons in stock - price is per button.

We use Australian coins for size reference - 5c, 10c, 20c and 50c or we provide a millimeter ruler for accurate sizing.

We are not button collectors, nor do we know a lot about them. Our drive is to keep as many of these beauties out of landfill. All of our buttons are sourced secondhand. Some are used, some are unused - some are very old (antique or vintage) and some are modern and new. There may be wear, tear and occasional discolouration, but if it's listed we consider the buttons still good enough to use and save from landfill. We'll list as much information as possible and provide close-up photos, but if you have further questions please don't hesitate to use the Contact Form or email vintagefabrics@gmail.com.
