These Powder Tubes are being manufactured for us in the traditional talc size 1 7/8" in diameter, 5" high. They hold 4 - 5 oz. of powder, depending on how dense it is (you'll need to weigh your product to ensure the correct weight on the label). The tubes themselves are made of cardboard lined with parchment paper (environmentally friendly!). The outside is a white semi-gloss paper - a reasonably neutral background for whatever you want to use as a label.
The top and bottom inserts are made of plastic. The top comes already in tube and the bottoms come loose with the tubes. The bottom insert is "friction fit"; it pushes in reasonably easily and won't come out on its own, but can be removed with a little judicious prying without damaging the tube itself.
See the article on Formulating Body Powder for tips on blending powders and filling powder shakers.
