Same premium quality as other Camera Butter filters, and fit in any slip-in filter mount that takes 33mm x 36mm filters (designed for the TBS Jello Guard.)  These are STRONGEST and toughest ND filter available anywhere, made out of super tough Gorilla glass.  

They also act as a lens protector - you cannot buy a stronger lens protector for your GoPro.    We also offer a clear (ND0) variant to use to protect your lens when you are not using an ND filter.

These universal neutral density filters are available in ND4, 8, 16 and 32. Also available in 3-piece multipacks: ND4, 8 and 16 or ND8, 16 and 32.  Producer pack (see below) is also available.

Extremely high quality ND filters made for GoPro Session 4/5 and Hero 4/5/6/7/8/9/10 , DJI Action 2, and any other camera mount with a slot for an ND filter. 

Not only are they much stronger than any other ND filter, but they have sublime optics, and have a special nano-coating that repels water, dirt and fingerprints and are much easier to clean than regular glass.

Whether you are using the ND filter for FPV drones, mountain biking footage or other action video, this will give you that smooth as silk, cinematic motion and reduce or eliminate jello.

Dimensions: 33mm x 36mm x 2mm thick 

TPU mount in picture is NOT included.  If you need a GoPro mount to fit the filters, you can get them at Brain3D.co
