Tru-Stone is manufactured from approximately 85% natural stone ore that has been pulverized to a powder and then mixed with pigments and acrylic resin. It is then compressed into blocks and cut to size. The finished product is a material that resembles the natural stone but can be turned and machined with standard wood tools. Each color varies in hardness, so for those new to this material please read the notes for each of of the colors. You can also see our help with turning page to see the method that we use to turn pens from Tru-Stone.

Bottle stopper blanks are available for several of the colors below. Those of you looking just for stopper blanks you can click here to see all that are available.

Notice: Pen blanks and stopper blanks have a tolerance of about 0.03" + or - the standard size. This doesn't affect most pen makers. But if your project requires absolute minimums, please contact me to make sure I can supply exactly what you need. Any standard blanks that come in outside of those tolerances are offered in the Odds and Ends section. Check those out here.
