Vermeil (gold plated sterling silver) bead cap in a simple 4 petal scrolled loop style. The cap size is roughly 12mm (inside dimesion). The cap is constructed in such a way that you can open or close the petals as you see fit for your particular size bead. Keep in mind that this does give you a certain flexibility that other caps cannot; but you will NOT be able to repeatedly bend the petals back and forth. The metal will break at some point. Cap is roughly 9mm tall. Hole size is 2.5mm.
