Sterling silver dulls with wear, and diamonds and gemstones collect oil and grime in the settings you can't easily reach. This bundle covers both: a silver polishing cloth that buffs tarnish off silver in a couple of minutes and a twist-nozzle cleaning pen that gets a brush and solution right behind and around your stones.
Keep them together in your jewellery box or bag, and you've got everything you need for a full clean between wears, no separate products or trips to a jeweller required. Buy the two together and save against buying them separately.
