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 pair is black and white. One charm is black and white, the other has black beads coated in clear frit (crushed glass) giving the beads a crunchy look.
