When I purchased this kit is was available in the US from Mazu on Amazon. Since then is has been made unavailable in the US (I can find it available in the UK strangely enough, but the listing is now called a 15-Piece set {No info about the instructional PDF}). But you can also find it on sites like eBay and Banggood. It doesn’t have a brand name but is easily recognizable. I also neglected to mention in the video that it comes with a shutterlock-wrench/tweezers thing that is almost useless and doesn’t really impact my review at all (it doesn’t fit in the case for what it’s worth).
