Small wax-coated paper baggies measuring 20mm-22mm wide that resemble a tiny lunch paper bag, that single units of heroin are packaged and sold in. They originally got their name because they were used to preserve collectible stamps and coins. They are found as glassine or vellum stamp collectors bags. They retain their name also because the logo or design of the drug "brand" is stamped on them with a solvent ink that does not bleed on wax (typically Stazon). The standard stamp bag contains 0.1 gram of powder heroin. Depending on the geographic area, stamp bags are sold in "bundles" of 10, 12, 14 or 20. Other names for stamp bags are slice, blue bag, nick, star.
