Keep your headset jacks clean and free of dust! These dust plugs are made with silver-plated & handmade glass beads. All glass beads are crafted one at a time on my oxy-propane torch, properly annealed and thoroughly cleaned. This is one of my favorite pairs. One charm has a pink and a purple spacer bead, while the other has pink beads with green melted in dots and raised light blue green dots. They're made from a special kind of German soft glass and the colors are really saturated.
