The Oneshot System is a unique no-mess disposable ink cartridge that also serves as a handle. When this cartridge is attached to the Oneshot roller or brush, a polypropylene membrane is pierced to allow the ink to flow. Proper ink saturation is controlled by a valve action pump. A plastic glove is included with replacement rollers to allow clean roller change over.
SI-RO-MARK fluid is the only sheep marking fluid approved as properly scourable by all of the world's leading wool processors.
The latest formulation has been tested by CSIRO and proven to be scourable--though obviously the most scourable mark is no mark at all.
SI-RO-MARK is available from sheep and wool supply firms throughout the USA. If you do not find it at your farm and ranch store, have them contact Premier. (We're the national importer and distributor.)
