Excellent brown pigment
Product came packaged in bag in a foil bag. No instructions but I figured it out with some Google help. It worked perfectly (turning white thinset into a nice dark brown). Will buy again when it's time for more repairs (this is setting stone into a waterfall + pond). One five pound bag of pigment was plenty/enough for a 50 lb bag of fortified thin set. Be careful, this stuff will dye anything it touches (clothes, gloves, tools, concrete floor, stone).

Well made
Straight up flat real brown coloring. Does not come out looking bronze. Easy to mix into resin and gives an opaque matte brown coloring.

Brown Oxide powder
This Brown Iron Oxide powder came in a bag that made it super easy to access when I needed it. The powder mixed easily into the plaster I was working with and you get a lot of it.

Easy to mix and nice coloring
This powder mixes in easy and looks good but it wasn't as bright as I was hoping.
