ZirJar is a must have if you are color dipping your full contour or substructure frame work. This 2oz flint glass jar has a patent pending silicone pad at the bottom of jar to prevent zirconia chipping and to keep the dipped restorations out of sediment which can effect the color. The easy to use flip lids allow a quick and safe way to open your coloring liquid jar. By never taking off and on your lids, you will not have to worry about putting the wrong shade lid on a jar. Also condensation and color liquid splash ends up on the bottom of the standard screw off lid and you end up getting color drips all over your work area that leads to cross shade issues. Increase work flow and lower remakes by using ZirJars.
