These black stretch bead bracelets are super easy to use. Just stretch them over your wrist and they'll fit snugly. You can wear them individually for a simple look or stack multiple bracelets for a more trendy style. When it comes to maintenance, keep them away from sharp objects to avoid scratching the beads. Also, don't expose them to harsh chemicals like perfume or cleaning agents, as these can damage the beads. If they get dirty, you can gently wipe them with a soft, dry cloth. Have fun accessorizing with these bracelets!
