Vintage "Mirror Glass" Flower Buttons, 3/8" / 10mm, #758

Small and sparkly, with paint behind clear carved sparkly diamond-like flowers, so there's a silvery mirror effect in these posies. They're a little over 3/8" in diameter; very small, and about 1/4" thick with the shank. Small sewing hole in the back. They're vintage but in excellent condition.  They do look and feel like glass and they were presented to us as glass, but they're very light in weight. They may be clear acrylic.  

$1.25 each.
