FNLite Means a Smaller & Lighter Bottle, with No Loss in Capacity

The Bunkerkings FNLite Carbon Fiber wrapped bottle line-up is engineered to be the lightest bottle you'll ever need. Simply screw your preferred 4500psi-rated HPA regulator on and get back to killing suckers. 

We've designed the the FNLite bottle to be up to 10% lighter and 9% shorter than the competition while still delivering the same number of shots with no loss in capacity? How do we do it? By using a proprietary DOT/ISO certified  carbon fiber wrapping technology around an aluminum liner, the FNLite shaves off weight and increases the inner volume at the same time.

With the FNLite, we've restored sanity to to bottle sizing that creates the perfect form factor and capacity for every player. Simply make your selection from four lightweight sized bottles: 60ci, 70ci, 80ci, or 90ci.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!

Works For Desired Use
Color: Black, Size: 4 Panel-136‘’W-Round Pad
I recently purchased the Room Divider 6FT Folding Privacy Screens, 4 Panel Partition Room Dividers, and I must say, it has transformed the way I use my living space. The four-panel design is both elegant and functional, providing instant privacy without feeling bulky or overwhelming in my room. Setting it up was a breeze; the folding mechanism is smooth, allowing me to adjust the configuration as needed—straight, angled, or zigzag. I particularly appreciate the sturdy build; the panels feel solid yet lightweight, making it easy to move around when I want to reconfigure my space. Aesthetically, it’s a great addition. The neutral finish blends well with my décor, and the simple design doesn’t draw too much attention while still offering a sense of separation. It’s perfect for creating a temporary office corner, dividing a studio apartment, or even using it as a backdrop for online meetings. If I had to point out a minor downside, it would be that the divider isn’t completely soundproof—so conversations can still carry through—but for visual privacy and space management, it’s excellent. Overall, I’m extremely satisfied and would recommend it to anyone looking for a versatile and stylish room divider.
