K&F CONCEPT Professional Lens Cleaning Pen*3 with Soft Brush, Carbon Head Lens Cleaning Pen Compatible with Canon, Nikon, Pentax, Sony Digital Camera Cleaning,AR VR Glasses Cleaning

Good size, good quality, and it clean the lenses and scopes very good and with ease, it works well. Great value for the money. Great product

A pack of pocket lens cleaners - great for smudges, fingerprint removal, or if you have a cellphone, that crud from your pocket. They are small and work well.

Overall the brush assembly works well for my occasional usage.

This lens cleaning pen is better than the K&F plastic option, in my opinion, because the carbon head cleaning connector is stronger. The bristles feel softer too. I don’t leave home without this.

Great for optics on firearms

Works perfectly

Love the aluminum body, both brush ends are of very high quality… Simply a must have item, don’t hesitate

The lens/sensor cleaning tip is the same as every other brand out there. I used this to clean the glass on pistol red dot optics. Just like every other optics cleaning pen it is never a good fit to clean the entire glass of the optic lense, especially the inside. Also, make 100% sure the glass has no debris of any sort unless you want to make the cleaning process 4x longer, or at worst scratch the glass. I also. Suggest getting a good coated glass/lens spray to really get it crystal clear. My steps for cleaning are, first I used compressed air to blow away any debris on both sides if the glass, then I spray both sides of the glass and wipe clean with an appropriate microfiber cloth (not all are created equal), then I use the pen to try and get any spots I missed with the microfiber cloth. If you get the pen tip wet, prepare for a nightmare of trying to clean a bunch of new smudges or haze on the glass. Nothing impressive or terrible about the product. If you have some sort of lens/sensor/glass cleaning pen already just stick with that.
