For the outdoor GoPro users a must!

One is with his GoPro eg on a motor cross track or in the deepest forest, in which the lens can easily get dirty, lens cover now has the perfect solution at hand.
Superimposed placeable protectors!
These keep the dirt on, save you from harsh cleaning processes, are easy to pull off and wipe the dirt off immediately. The superposition place of films would not negatively impact on the result of film!

One has only to note that each pulling a film cost almost EUR 1.00 since 12 films are included in the package for 12 euros. Too much dirt which can then be expensive.
