These are small thin clothes exactly like you often get when you buy new glasses. They can be re-used (just be sure to wash them separately so they do not pick up lint in the wash). It is nice that these come securely and individually wrapped so I can keep a new pristine one with me in my bag. Perfect for phones and laptops and such but I mainly used for my eyeglasses.

These are very cool. They are slightly smaller and thinner than the typical camera microfiber cloth but silky smooth and big enough for use. Contained in a vacuum-sealed package, you can carry these in your pockets and camera bags without concern about keeping them perfectly safe, so that they can be used on your equipment with no dust and oils on them. The outdoors can be a humid, sweaty, and rainy place to be in, so it's great to have these clothes prepared in a sealed-package. Once opened, they seem to expand a bit and are ready to go. I tried them out and they are perfectly fine on lenses and filters. These cloths are dry, not premoistened, but cool to the touch compared to the surrounding room temperature. I would like to see an alternative product just like this that has a slight moisture content of distilled water, maybe with a little bit of no-residue rubbing alcohol, as these would be great to-go so you don't have to prepare or carry cleaning solutions or water. These would make a great gift for any photographer, filmographer, or an owner of glasses, goggles, binoculars, or telescopes. They can also be useful to store in a vehicle. Being that these are individually wrapped, you can hand them out to students or in gift bags, or gift the whole box itself which comes in a plastic shrink wrap seal. This product is only $9 and you get 10 vacuum-sealed microfiber cloths, so that's a pretty good price as well. K&F is also a brand of what I would consider to be high-end filters, tripods, and other photographic equipment, so this is a dependable company. Even if you buy this as a small gift for your photographer friend, the brand name and logo on its attractive presentable packaging will have a big impact, and everyone can always have more microfiber cloths around. So they're highly functional and giftable at a low price.
