The Nikon LC-52 is a Snap-on Front Lens Cap for lenses that have a 52mm filter thread.
It snaps onto select NIKKOR lenses, protecting the front element from dust and scratches when not in use.

Xtech Universal Lens Cap Keeper is an elastic cord that goes around your lens and a small circular stick-on piece that goes on your lens cap to hold it so you wont lose it anymore.

HeroFiber Ultra Gentle Cleaning Cloth:
HeroFiber is the most efficient way to clean all optical surfaces.
HeroFiber acts like a magnet for dust, dirt, and oils, so it absorbs without being abrasive or leaving residue, and lasts considerably longer than ordinary cloths.
